A E_R_R_O_R_ _M_E_S_S_A_G_E_S_
A.1 I_n_t_r_o_d_u_c_t_i_o_n_
The errors that can occur during use of the RC BASIC system fall
into three categories.
1) E_r_r_o_r_s_ _d_e_t_e_c_t_e_d_ _d_u_r_i_n_g_ _p_r_o_g_r_a_m_ _e_n_t_r_y_ _o_r_ _c_o_m_m_a_n_d_ _e_x_e_c_u_t_i_o_n_
If an error is detected when an RC BASIC statement is entered or
when a command is executed, an error message will be output in
the following form:
ERR : xxxx'
text'
xxxx': a decimal error code less than 0100.
text': a brief description of the error.
If an error is detected while a program is being read from a
file, RC BASIC will output the erroneous statement followed by
the above error message on the current output device.
2) E_r_r_o_r_s_ _d_e_t_e_c_t_e_d_ _d_u_r_i_n_g_ _p_r_o_g_r_a_m_ _e_x_e_c_u_t_i_o_n_
If an error is detected during the execution of a program, an
error message will be output in the following form:
AT yyyy' :
ERR : xxxx'
text'
yyyy': the line number of the erroneous statement.
xxxx': a decimal error code less than 0100.
text': a brief description of the error.
3) E_r_r_o_r_s_ _d_e_t_e_c_t_e_d_ _d_u_r_i_n_g_ _f_i_l_e_ _o_p_e_r_a_t_i_o_n_s_
If an error is detected during an input/output operation, an
error message will be output in a form similar to that of the
messages output for errors of the first or second category;
however, the text IOERR will replace the text ERR and the\f
decimal error code, xxxx', will be greater than or equal to
0100.
E_r_r_o_r_ _m_e_s_s_a_g_e_s_,_ i.e. messages for errors detected during program
entry or command execution as well as those detected during
program execution, are listed and explained in numerical order
in Section A.2 and A.4.
I_/_O_ _e_r_r_o_r_ _m_e_s_s_a_g_e_s_,_ i.e. messages for errors detected during
file operations, are listed and explained in numerical order in
Section A.3.

an overflow when the AUTO command is used. \f
0006: TOO MANY NAMES
Too many names (variables and procedures) have been
declared. The maximum number allowed is 93. The number
of names can be reduced by means of the following

The batch mode of operation permits the user to enter and run
one or more complete jobs from the mark-sense card reader (when
present).
RC BASIC source programs, written on mark-sense cards, are
placed in the reader; when the BATCH/BATCH "<LPT" command is
given from a terminal, the system starts reading the cards.
The cards, t_h_e_ _c_o_n_t_e_n_t_s_ _o_f_ _w_h_i_c_h_ _a_r_e_ _i_n_t_e_r_p_r_e_t_e_d_ _e_x_a_c_t_l_y_ _a_s_ _i_f_

BASIC statements and commands with few exceptions.
A stack of cards for batch entry is typically divided into
several jobs.
Each job is initiated by a card containing a SCRATCH command
(see Sect. B.5) and terminated by a card containing the EOJ
command (see Sect. B.4).
Between the SCRATCH command and the EOJ command there can be an
RC BASIC source program on cards, each of which contains one
statement, and following the program there can be one or more
cards containing one command each, e.g. LIST and RUN.
A RUN command may be followed by cards containing data for the
program, which is read by means of INPUT statements (see Ch. 3)
in the program. Such data cards are marked only in the FORMULA
section of the card (see Sect. B.2).
The figure below shows a card stack containing two batch jobs.

F_ B.2M_a_r_k_-_s_e_n_s_e_ _c_a_r_d_s_
The cards used for batch jobs are 37 column mark-sense
programming cards. The RC BASIC mark-sense card looks like this:
S_T_A_T_E_M_E_N_T_ _2_
F_O_R_M_U_L_A_
S_T_A_T_E_M_E_N_T_ _1_
S_T_A_T_E_M_E_N_T_ _N_U_M_B_E_R_
\f
F_ The mark-sense card is not punched; instead, information is
written on it simply by marking one or more fields with a_ _s_o_f_t_
p_e_n_c_i_l_, e.g. No. 2.
As may be seen from the figure on the preceding page, the
RC BASIC mark-sense card is divided into four sections, from
left to right:
STATEMENT NUMBER section (columns 1-4)
STATEMENT 1 section (columns 5-7)
FORMULA section (columns 8-36)
STATEMENT 2 section (column 37)
b_ B.2.1 S_T_A_T_E_M_E_N_T_ _N_U_M_B_E_R_e_
The STATEMENT NUMBER section (columns 1-4) is used for statement
numbers.
An RC BASIC program consists of statements, each of which begins
with a statement number in the range 1 to 9999. A statement
number is written by making at the most one mark in each of the
columns 1 to 4.
\f
F_ E_x_a_m_p_l_e_s_
10 : 1987:
b_ B.2.2 S_T_A_T_E_M_E_N_T_ _1_ e_
The STATEMENT 1 section (columns 5-7) permits the user to write
one or more RC BASIC words simply by marking one field for each
word.
None of the three columns in this section may contain more than
one mark. Some of the RC BASIC words are commands, e.g. LIST or
RUN, and may not be preceded by a line number. Other words, e.g.
ENTER or CLOSE, may be used with or without a line number, i.e.
either as statements or commands. Still other words can be used
only with a line number, e.g. PROC or ENDPROC.
Whether a word must have, may have, or may not have a line
number can be seen from the statement and command descriptions
found in Chapters 3, 6, 7, 8, and 9.

F_ E_x_a_m_p_l_e_s_
10 OPEN FILE : LIST :
b_B.2.3S_T_A_T_E_M_E_N_T_ _2_e_
The STATEMENT 2 section (column 37) is used as follows:
The C_O_N_T_ _f_i_e_l_d_ should be marked whenever an RC BASIC statement
fills more than one card. The system will then continue reading
from the next card, s_k_i_p_p_i_n_g_ _t_h_e_ _S_T_A_T_E_M_E_N_T_ _N_U_M_B_E_R_ _s_e_c_t_i_o_n_ _o_f_
t_h_a_t_ _c_a_r_d_._ A statement can theoreticallybe continued on any
number of cards.
When the E_O_J_ _f_i_e_l_d_ is marked, the system will terminate the job.
No other fields on the card should be marked.
The T_H_E_N_,_ _O_F_,_ _a_n_d_ _D_O_ _f_i_e_l_d_s_ are used in conjunction with the
words IF, CASE, and WHILE, respectively.
E_N_D_P_R_O_C_,_ _R_E_T_U_R_N_,_ _S_T_O_P_,_ _E_N_D_,_ _a_n_d_ _R_A_N_D_O_M_I_Z_E_ are normal RC BASIC
statements.
\f
F_ The STATEMENT 2
section looks
like this:
b_ B.2.4 F_O_R_M_U_L_A_ e_
The FORMULA section (columns 8-36) is used for that part of an
RC BASIC statement which cannot be written in the STATEMENT 1
and STATEMENT 2 sections.
Each of the columns 8 to 36 contains twelve vertical fields.
The first field from the top is field number 12, the second
field from the top is field number 11, and the remaining fields
are numbered 0 to 9.
B.2.4.1 E_v_e_n_ _n_u_m_b_e_r_e_d_ _c_o_l_u_m_n_s_._ Columns with even numbers (i.e. 8, 10,
..., 36) are used for the letters A to Z, the digits 0 to 9, and
the following special characters:
= (field 12)
, (field 11)
. (field 9)
B.2.4.2O_d_d_ _n_u_m_b_e_r_e_d_ _c_o_l_u_m_n_s_._ Columns with odd numbers (i.e. 9, 11,
..., 35) are used for the digits 0 to 9 and the following
characters:\f
F_ ( (field 12)
) (field 11)
+ - * (field 1)
/ ; (field 2)
' # (field 3)
" : < (field 4)
? % Æ (field 5)
& ! SP (field 6)
@ Ø Å (field 7)
CR " (field 8)
= , . (field 9)
N_o_t_e_: SP is the space character. CR outputs positioning to the
leftmost character position on the print line a_n_d_ _a_ _l_i_n_e_ _f_e_e_d_
(see App. D). @, Ø, and Å are letters of the Danish alphabet.
B.2.4.3 W_r_i_t_i_n_g_ _c_h_a_r_a_c_t_e_r_s_._ The following characters are (or may be)
written by marking only one field:
= (field 12, even numbered columns)
( (field 12, odd numbered columns)
, (field 11, even numbered columns)
) (field 11, odd numbered columns)
0 to 9 (fields 0 to 9, respectively)
All other characters are written by marking two fields:
The f_i_r_s_t_ _f_i_e_l_d_ to be marked is the field in which the
character itself appears on the card.

F_ The s_e_c_o_n_d_ _f_i_e_l_d_ to be marked is field 12, 11, or 0.
Which second field to mark is determined by the position of
the character in the first field, for example:
_______
A
B 1
_C______
The characters A, B, and C all appear in field 1.
Since the character A has the t_o_p_ _p_o_s_i_t_i_o_n_ in field 1, it is
written by marking field 1 a_n_d_ _f_i_e_l_d_ _1_2_.
Since the character B has the m_i_d_d_l_e_ _p_o_s_i_t_i_o_n_ in field 1, it
is written by marking field 1 a_n_d_ _f_i_e_l_d_ _1_1_.
Since the character C has the b_o_t_t_o_m_ _p_o_s_i_t_i_o_n_ in field 1, it
is written by marking field 1 a_n_d_ _f_i_e_l_d_ _0_.
\f
F_ E_x_a_m_p_l_e_
The statement

1. Blank spaces must be marked explicitly (the character SP).
Columns having no marks whatsoever will be skipped by the
card reader.
2. If a column contains more than the legal number of marks, the
column will be skipped. (This can be utilized to skip a
column containing an incorrectly marked field). Columns 1-7
may contain only one mark. Columns 8-36 may contain two
marks. Column 37 may contain a mark in the CONT field and one
other mark.
3. RC BASIC words not found in the STATEMENT sections can be
written using the FORMULA section.

A terminal can be placed in batch mode by giving the command
BATCH or BATCH "LPT". Before the command is given, the cards
should be placed in the card reader and the reader should be
ready, as the system will start reading cards at once.
If the BATCH form of the command is used, all output from the
jobs executed, i.e. listings, output from PRINT statements (see
Ch. 3), and error messages, will appear on the terminal.
If the BATCH "LPT" form of the command is used, job output will
be directed to the line printer.

As stated in Section B.1, there are a few RC BASIC statements
and commands which cannot be used in batch mode. They are:
AUTO
BATCH/BATCH "LPT"
BYE \f
F_ b_B.3.3T_i_m_e_ _l_i_m_i_t_ _o_n_ _j_o_b_s_e
A time limit can be placed on a job, so that when the job has
run for a specified number of seconds, it will be interrupted.
The error message 0010: TIME LIMIT EXCEEDED will then be output
and the next job started.
The next job is assumed to begin with a SCRATCH command.
When a job is started, the time limit is set by default to
60 seconds. This time limit can be changed by means of the TIME
command (see Sect. B.6).
b_ B.3.4 E_S_C_a_p_e_ _k_e_y_ e
The ESCape key has a special function when the terminal is in
batch mode.
When the ESCape key is pressed, the system will interrupt all
current activity and output the following message on the
terminal:
NEXT JOB(1), END OF BATCH(2), CONTINUE(3):
Here, the user should respond by typing one of the numbers
(i.e. 1, 2, or 3) and pressing the RETURN key.
All according to the user>s response, the following will now
occur:
1 Cards will be read and skipped until
a SCRATCH command is encountered or the
reader is empty.
2 The terminal will be placed in
interactive mode.
3 The next card will be read and its
contents interpreted.
b_B.3.5 R_e_t_u_r_n_ _t_o_ _i_n_t_e_r_a_c_t_i_v_e_ _m_o_d_e_e
When the BATCH/BATCH "LPT" command has been given, theterminal
will remain in batch mode until one of the following occurs:
\f
F_ 1. The card reader becomes empty.
2. The user presses the ESCape key and then
types the number 2.
3. An I/O error on the card reader is detected.
B.4 E_O_J_ _c_o_m_m_a_n_d_
F_o_r_m_a_t_
EOJ
U_s_e_
As a command to terminate a job.
R_e_m_a_r_k_s_
1. The EOJ command executes an implicit NEW command (see Ch. 9).
2. Any logical disc that was connected by the job will be
RELEASEd (see Ch. 7).
3. A card containing the EOJ command should always be the last
card in a job.
B.5 S_C_R_A_T_C_H_ _c_o_m_m_a_n_d_

SCRATCH text'
text': a text, i.e. a number of characters, which will
be output as a heading.
U_s_e_
As a command to initiate a new job.
R_e_m_a_r_k_s_
1. If the command BATCH (see Sect. B.3) has been given, the\f
F_ SCRATCH command will clear the display screen on the RC 822
or RC 823 terminal; if the command BATCH "<LPT" has been
given, SCRATCH will cause the output of a form feed (see App.
D) on the line printer.
2. If text' is specified, text' will be output as the first
line displayed on the terminal or the first line on the new
line printer page.
3. The job time limit is set to 60 seconds. This time limit can
be changed by means of the TIME command (see Sect. B.6).
4. An implicit NEW command is executed (see Ch. 9).
5. Any logical disc that was connected by the previous job is
RELEASEd (see Ch. 7).
6. A card containing a SCRATCH command should always be the
first card in a job.
B.6T_I_M_E_ _c_o_m_m_a_n_d_

TIME=val'
val': a numeric constant (expressing seconds).
U_s_e_
As a command to specify how many seconds a job may run.
R_e_m_a_r_k_s_
1. If the TIME command is not used, the system will interrupt
the job in 60 seconds, starting from the execution of the
SCRATCH command (see Sect. B.5).
2. The maximum specifiable time limit is 3600 seconds (1 hour).
3. The time allotted to a job is real time, i.e. the amount of
central processing unit time which the job actually receives
will depend on how many programs are being run at the same
time from terminals in interactive mode. \f

The interactive use of RC BASIC for source program maintenance
is described in Chapter 9. This appendix describes other
interactive uses of RC BASIC.
Many RC BASIC statements (see Chs. 3, 6, and 8) can be used as
keyboard commands. When a statement is used as a command, it is
entered without a preceding line number and terminated by pres-
sing the RETURN key; the system then executes it immediately.
This facility is useful for:
Performing desk calculator functions, e.g. PRINT EXP(2.13)
Debugging programs dynamically
Performing file input/output, e.g. OPEN FILE(6,9) "PTR"
Certain RC BASIC statements, which are meaningful only within
the context of a program, cannot be used as keyboard commands.
These statements are:
CASE-WHEN-ENDCASE ELSE
DATA ON-ERR
DEF ON-ESC
DELAY ON-GOTO/GOSUB
END PRINT USING
EXEC PROC-ENDPROC
FOR-NEXT REM
GOSUB and RETURN REPEAT-UNTIL
GOTO STOP
ENDIF WHILE-ENDWHILE \f
F_C.2D_e_s_k_ _c_a_l_c_u_l_a_t_o_r_ _f_u_n_c_t_i_o_n_s_
Calculations can be performed using the PRINT command. A
semicolon (;) may be used instead of the word PRINT.
The items in the argument list may be numeric or relational
expressions, string literals, or string variables.
Values can be assigned to variables by means of the LET, INPUT,
or READ command, or the current values of variables in a loaded
program can be used.

C.3P_r_o_g_r_a_m_ _d_e_b_u_g_g_i_n_g_
The use of RC BASIC statements as keyboard commands permits
programs to be debugged dynamically.
If, for example, a running program is producing the wrong
output, it can be interrupted (ESCape key); the current values
of the variables can then be examined (PRINT command) and
changed (LET command) as required, before program execution is
continued (see the CON or RUN line no.' command, Ch. 9).

With the exception of PRINT FILE USING, the file input/output
statements described in Chapter 8 can be used as keyboard
commands to create a file, open a file, write data to a file,
and so on.
If, for example, the error message 0129: I/O, FILE NOT OPENED is
output, the user can open the file by means of the command
OPEN FILE(file',mode') filename'
and program execution can then continue.

Non-printing characters, i.e. characters which do not appear as keys
on the terminal keyboard, can be output by means of the following
sequence:
PRINT "x'"
where x is the decimal value of the character to be
output.
Only a few of the non-printing characters are used ordinarily,
e.g. to move the paper on the line printer or to position the cursor
on a video terminal.
The non-printing characters that occur most frequently are:
12 FF Form Feed. On the line printer, feeds the form
to the top of the next page and positions to
the leftmost character position on the print
line.
13 CR Carriage Return. On the terminal, positions to
. the leftmost character position on the print
line.
10 LF Line Feed. On the terminal, feeds one line
vertically.
N_o_t_e_: To output positioning to the leftmost
character position on the print line a_n_d_ a line
feed, the sequence PRINT "13'10'" must be
used.
7 BEL Bell. On the terminal, causes the bell to ring
once.
The characters used to position the cursor on a video terminal
will depend on the terminal in question and may be found in the
operating guide for the terminal.

T_ G.4 FILEROUTER OPERATING GUIDE
The basic system consists of three internal processes called
basic, filerouter and tem.
&_ The program running in the basic process contains action for
building, translating, executing and debugging of programs written
in the comal language. This program also performs the operations
upon files on backing storage. \f
The program running in the tem process performs a transformation
of the multiple data streams to displays and from keyboards into a
single stream of data from and to the basic process.
The program running in the filerouter process performs the
following operations:
T_ a) Printing of text; data produced by comal programs upon the
line printer.
b) Punching of text data produced by comal programs upon the
paper tape punch.
c) Reading of text files residing on paper tape from the paper
tape reader or from paper tape reader on tty consoles.
d) Reading of text data from the cardreader.
e) Copying of data from an input device to an output device or
to and from backing storage text files.
&_
To do this the filerouter operates the local devices known in the
RC 8000 system as printer punch, reader and cardreader.
In the following the communication between the operator and the
filerouter due to change of paper, loading of data files etc. is
described.
The filerouter uses the operator console i.e. the console from
which the filerouter process was created for this communication.
P_r_i_n_t_e_r_
The filerouter knows the device as device number 1.
Whenever the printer is needed and out of paper, in remote state,
power off or disconnected the following message appears on the
operator console:
basic filerouter printer out of paper answer no. 1
The operator is now assumed to correct the error and then notify
the filerouter by pressing the escape key (att) and type
att filerouter
**answer 1
P_u_n_c_h_
The filerouter knows the devices as device number 2. \f
Whenever the punch is needed, the following message appears on the
operator console:
basic filerouter punch clear for user' projectnumber' answer no.
2
The operator is now assumed to convince himself that the punch is
ready and then notify the filerouter by pressing the escape key
and type:
att filerouter
**answer 2
The punch may run out of paper. The procedure is as follows:
basic filerouter punch out of paper answer no. 2
Place new paper tape in the punch and type:
att filerouter
**answer 2
R_e_a_d_e_r_
The filerouter knows the device as device number 3.
Whenever the reader is needed, the following message appears on
the operator console:
basic filerouter reader load for user' projectnumber'
The operator is now assumed to place the paper tape marked user'
projectnumber' in the paper tape reader and press the reset
button.
C_a_r_d_r_e_a_d_e_r_
The filerouter knows the devices as device number 4.
Whenever the cardreader is needed, the following message
appears on the operator console.
basic filerouter cardreader load for user' projectnumber'
The operator is now assumed to place the card deck marked user'
projectnumber' in the cardreader. If the carddeck is composed of\f
marked sense cards the switches on the back at the cardreader must
be in positions opt mark and clock, otherwise positions punch and
non-clock are choosen.
Then press the reset button.
T_t_y_ _p_a_p_e_r_ _t_a_p_e_ _r_e_a_d_e_r_ _(_t_r_a_n_s_m_i_t_)_
The filerouter knows the device as device number 5.
Whenever a comal user requests reading of a paper tape from the
paper tape reader on his console, the following message appears on
this console:
basic filerouter start transmit
Now the comal user is supposed to place a paper tape in the reader
and press the start button. If this is not done within about 30
seconds the console returns to interactive mode.
A_u_x_i_l_i_a_r_y_ _c_o_m_m_a_n_d_s_
Besides the answer commands, the following commands may be used by
the operator of the filerouter.
T_ Display device number'
Clean device number'
Start device number'
&_
where the value of device number range from one to five indicating
printer, punch, reader, cardreader and transmit.
T_ D_i_s_p_l_a_y_
If the device is not used nothing is answered otherwise the queue
of pending requests are displayed to the operator e.g.
queues of
printer
number of requests: 3
number of requests for which answer has not been sent: 0
&_ \f
T_ user project bsareaname lowerbase upperbase
ta 4 fut 1420 1429
kc 4 comal 1410 1419
pas 4 frtesttxt 1400 1407
&_
the requests listed by user name, projectnumber etc. are those
originating from the comal users use of the copy command. Number
of requests for which answer has not been sent originates from the
comal users use of the open and close statements. The requests are
not listed only the number of them are shown.
T_ C_l_e_a_n_
The queue of pending requests to the device is displayed to the
operator e.g.
att filerouter
**clean 1
produce
queues of
printer
&_
number of requests: 3
number of requests for which answer has not been sent: 0
T_ user project bsareaname lowerbase upperbase
ta 4 fut 1420 1429
kc 4 comal 1410 1419
pas 4 frtesttxt 1400 1409
current transaction
&_
T_ user project bsareaname lowerbase upperbase
mater 4 characters 1400 1499
&_
Then all requests are removed from the queues of the device and
the device is placed in skip mode, i.e. future requests are
rejected.
The requests originates from copy commands (ta, kc, pas) are
hereby removed without notifying the user, which the operator is
supposed to do. This should be done for the current transaction
too, as the operator cannot know whether this user is notified by
the system or not.
\f
S_t_a_r_t_
A device which has been placed in the skip mode may be restarted
in the sense that requests are no longer rejected by use of the
start command e.g.
att filerouter
**start 1
T_ S_u_m_m_a_r_y_ _o_f_ _c_o_m_m_a_n_d_s_
The syntax of commands to the filerouter is:
filerouter command'::=keyword'space'device number'
keyword'::=answ clea disp star
device number'::=1 2 3 4 5
Command input i.e. response to the ** which is not a filerouter
command is ignored by the filerouter.
&_
T_ G.5 INSTALLATION
The following files must be present:
1) tem ; an operating system
2) frprog ; the filerouter program
3) xcomal ; the basic interpreter
4) usercat ; a catalog defining the users disc claim.
&_ 5) basicerror ;a file containing the error message.
To define the user claims, the BOSS program CATUPDATE (see BOSS
Installation and Maintenance) is used.
A project with a user named operator must exist.
T_ For each project:
1) Record type 10: Project width'= number of users
2) If a special standard kit is desired for this project,
then specify a record type 4, specifying 0 slides, 0 entries
3) For each user in the project.
1) Record type 11: job width and user indices should be 1
(not a demand), except for the MATER who has a job width
embracing all users.
2) For each desired kit is specified a record type 9 or 4.
3) Record type 0 for end of user
&_
Other record types are allowed but will not be used by COMAL. \f
It will be possible to use this usercat from BOSS.

The keyboard used with RC700 and RC850 is a selfcontained unit
supplied from +5 Volt through the interconnection cable.
When used with RC850 the interface is a serial interface and when
used with RC700 it is a parallel interface. The output from the
keyboard may be a position code or an ASCII code. The ASCII code
may be defined in the keyboard program or it may be specified by
a separate custom PROM. ASCII code is normally used together with
parallel interface.
Switches or straps on the board select the different modes for
interface and code.

The keyboard is supplied with a bell/click connector which con-
nects the keyboard to a switch, a potentiometer and a loud-
speaker. The circuit diagram for the circuits on the keyboard and
the components supplied to the connector are shown in fig. 1.
The connector may be of the following type:
AMP type 102162-1
3M - 3491-1003
When control A is high, a signal at approx. 2.2 kHz is sent to
the loudspeaker. This is the bell function.
When control B is high, a signal at approx. 1.6 kHz is sent to
the loudspeaker if the switch is on.
This makes the click function. This is activated in approx. 3.5
msec.
The potentiometer controls the signal amplitude for both func-
tions.

keyboard and the host, when serial communication is selected.

In serial mode the keyboard may be initialized. For each keyposi-
tion on the keyboard, the key will deliver a predefined binary
code when pressed. For keys like shift and lock it may be wanted
to get an output signal too, when the key is released. This out-
put code must be initialized. The maximum number of keys with
such a double code is 15.
Before initializing the double code keys, the double key pointer
internally in the keyboard must be reset. This is done by sending
the following sequence to the keyboard:
byte 1 D5 Hex
- 2 C0 -
- 3 FF -
- 4 FF -
Then it is possible to initialize 1 to 15 double keys using the
following sequence for each key:
byte 1 C0 Hex
- 2 Key position number
- 3 Release code from key
E_x_a_m_p_l_e_:
The keyboard receives the following sequence:
byte 1 C0 Hex
- 2 A0 -
- 3 B3 -
\f
The result is that the key with the key code number A0 (see fig.
2) is initialized to be a double code key with the release value
B3 Hex. Input codes not mentioned here or in the appendices
should be ignored.

release code does not change the output code for the key when
pressed.

The keyboard may be supplied with a number of LED's (light emit-
ting diodes) which may be turned on and off using one of the
following commands. The audio circuit (bell function) is used the
same way.

F_ Audio is controlled by command 3 bit 3. Setting bit 3 to one
turns control A (bell) on as described in chapter 5 and shown in
fig. 1.
The different lamp positions are shown in fig. 3. A lamp may be
placed hardware-wise in any of the number positions shown. Only
one lamp may be used for each number.
E_x_a_m_p_l_e_:
The byte 81 Hex selects command 3 and sets LED number 12 to
light. When this byte is sent, an LED in the position marked 12
in fig. 3 is lighting. The byte 80 Hex turns it off again.

When a key is pressed, a character containing the output code is
sent as shown in section 6.2. If a key is pressed for more than
0.7 sec. the auto-repeat function starts. This function is shown
in fig. 4.
The auto-repeat function is not wanted for all the keys. The keys
with output code 60 Hex, 80 Hex, 81 Hex, A0 Hex, C6 Hex, C0 Hex,
C1 Hex, CB Hex and C4 Hex are normally made without auto-repeat.
As the keyboard is made using a microprocessor, it is possible to
change the program in the keyboard and remove the auto-repeat
from other keys.
Whenever a character is sent, the control A (click) is on for
approx. 3.5 msec. Using the circuit shown in fig. 1, an acoustic
signal is generated whenever the a key is activated on the key-
board.

Fig. 5 shows the output from the different keys. The two hexa-
decimal numbers show the value when shift is not pressed (normal)
and when pressed (shift).
The alphalock key is supplied with a red light showing when the
keyboard is in alphalock mode. In this mode the shift value is
selected for those keys which in the figure are marked with an X.
The other keys are not effected by the alphalock key.
When the CTRL key is pressed and another key is pressed too, the
output from this key is between 00 Hex and 1F Hex. This means
that the 3 most significant bits are set to zero.

The keyboard is supplied with socket for an extra PROM (2716),
which may contain another ASCII table, than the one shown in fig.
5. A strap selects this PROM which the user has to program.

The keyboard is supplied in many layouts and in many national-
ities.
The following 3 figures show some of the more often used ver-
sions.
In some situations it is wanted to change the nationality of the
keyboard simply by changing a number of keytops.
The keyboard may also be supplied in a short version (without
numeric block). This is shown in fig. 9.

The following identification function (ID function) is not imple-
mented on the keyboard first delivered to RC Computer. The func-
tion is to be used only when serial mode of operation is select-
ed. The ID function works the following way:
The Keyboard is equipped with 8 dip switches, the setting of
which the host computer is able to read. The switches may carry
information about the nationality of the keyboard layout etc.
The switches may be read sending a READ SWITCHES command to the
keyboard. Then the keyboard returns the switchsetting. To be sure
that the switchsetting is read, and not an operator pressing a
key, the program ignores the keys for a time period when the
switches are read. See fig. 12.
The READ SWITCHES command is: E0 Hex
The replay is:

Bit 0 = logical one when switch 0 (SO) is on and logical zero
when switch 0 is off, etc.

This document is intended as an introduction to the UCSD PASCAL
system running on the RC700 microcomputer.
Only details specific to the RC700 implementation of UCSD PASCAL
is covered.
For detailed information about the UCSD Pascal system and the
PASCAL language please refer to the references in appendix A.
The system delivered from A/S Regnecentralen af 1979, is a CP/M
adaptable UCSD PASCAL system from SofTech Microsystems configured
to run on the RC700 microcomputer.
The distribution system is configurated for one drive and has no
floating point facilities. The configuration may be changed by
the user in choosing a suitable interpreter module, see chapter
3.
The distribution system is too configurated for use with a Danish
keyboard. The user has to specify the conversion table corre-
sponding to the actual keyboard used, which may be done when pro-
ducing a copy of the distribution system, see chapter 2.
You are kindly advised to produce a copy of your distribution
system as the very first thing to do.
If you have any problems with the system please contact your
RC700 Support Center.

A save copy of your system may be generated in several ways. In
this section a description is given of how to make a one to one
copy (except for the keyboard-conversion-table) of the distribu-
tion set delivered. When created the copy-set should be used as
work-set and the distribution set (your master set) should be
saved.
The MAXI-distribution set consists of two diskettes, the loader
diskette and the system diskette. The loader diskette is a type 1
diskette and the system diskette is a type 2 diskette (see chap-
ter 4).
The MINI-distribution set consists of four diskettes, one loader
diskette and three system diskettes. The system diskettes are
configurated with different catalogs (named SYS:, SYS1: and
SYS2:) and labelled 1 of 3, 2 of 3 and 3 of 3.
In app. B, C and D a detailed description is given of how to
generate a copy of your system.
In a MAXI-system use the 'loader diskette copy procedure' of
app.B (Keyboard-conversion-table generation included) and then
the 'system diskette copy procedure' of app. C.
In a MINI-system you have to preformat your new (scratch-)disket-
tes before used. For that reason start with the 'formatting pro-
cedure' of app. F. Continue with the 'loader diskette copy
procedure' of app. B and finish with the 'system diskette copy
procedure' of app. D.
\f

The UCSD PASCAL system is loaded in the following way:
1) Insert the diskette marked 'PASCAL LOADER' into drive 1 and
press the 'RESET'-button.
The following text will be printed:
RC700 PASCAL LOADER vers. XX
INSERT PASCAL DISK - TYPE <RETURN>
2) Insert the PASCAL system load disk (SYS:) into drive 1, and
type <return>. After several disk accesses, the PASCAL prompt
line will appear, and the system is ready for use.
NOTE: The system needs 64 k bytes of memory!
The PASCAL disk to be bootstrapped must contain a secondary
bootstrap on track zero and the following files:
SYSTEM.PASCAL (the operating system)
SYSTEM.INTERP (the PASCAL interpreter)
SYSTEM.MISCINFO (information about terminal handling)
The available PASCAL-programs - to example the compiler - may
require some additional files to exist on SYS:, see chapter 7.
Please notice that your present RC700 PASCAL does not support
neither the 'serial line input/output' nor the 'additional disk
drives', see ref 1, p8.

The initial configuration of the PASCAL interpreter (the file
SYSTEM.INTERP) is able to handle 1 floppy disk drive and has no
floating point capabilities.
Three more interpreter module files exist:
CMP2.INTERP
2 drives supported -
no floating point capabilities.
CPM1.FP.INTERP
1 drive supported
floating point included
CPM2.FP.INTERP
2 drives supported
floating point included
The INTERP modules occupies much less memory space than the
FP.INTERP modules.
To install a new interpreter, enter the F)iler by typing F, and
R)emove the file SYSTEM.INTERP. Then T)ransfer the appropriate
interpreter file to the system disk, naming it SYSTEM.INTERP. The
system may now be re-booted, thus including the new interpreter
module.
A detailed description of the reconfiguration procedure is given
in app. E.
NOTE: if a two disk version is generated and a system load is
performed, a diskette must be in both drives in order to prevent
the system from hanging on a read to the second drive.\f

MAXI-diskettes are delivered as preformatted diskettes. A number
of various formats are used. In the PASCAL-system you deal with
two types as explained below.
MINI-diskettes are delivered as non-preformatted diskettes. Thus
they must be preformatted before use. In app. F a detailed
description is given of how to format the diskettes. Only one
format is used.
4_._1_ _ _ _ _ _ _ _L_o_a_d_e_r_ _D_i_s_k_e_t_t_e_s_ 4.1
Format description (one cylinder = two opposite tracks for double
sided diskettes):
The MINI-diskette (5 1/4" floppy):
Single density, double sided, 128 bytes per sector, 16 sectors
per track, 36 cylinders.
The MAXI-diskette (8" floppy):
Single density, single sided, 128 bytes per sector, 26 sectors
per track, 77 cylinders.
This MAXI-diskette is referred to as a type 1 diskette.
4_._2_ _ _ _ _ _ _ _S_y_s_t_e_m_ _D_i_s_k_e_t_t_e_s_ 4.2
Format description (one cylinder = two opposite tracks for double
sided diskettes):
The MINI-diskette:
Single density, double sided, 128 bytes per sector, 16 sectors
per track, 36 cylinders. Thus it can hold 280 PASCAL blocks (512
bytes per block).
\f
The diskette is formatted with 2 to 1 interleaved sectors and
zero track to track skew, and the first PASCAL track is track
one.
The MAXI-diskette:
Dual density, double sided, 512 bytes per sector, 15 sectors per
track, 62 cylinders. Thus it can hold 1830 PASCAL blocks (512
bytes per block). This MAXI-diskette is referred to as a type 2
diskette
The diskette is formatted with 2 to 1 interleaved sectors and
zero track to track skew, and the first PASCAL track is track
one.
Diskettes not having the proper interleaving ratio and track to
track skew must be reformatted using the DISKCHANGE program (see
ref. 1) before used by the system.
\f
F_ 5_._ _ _ _ _ _ _ _ _S_Y_S_T_E_M_ _U_T_I_L_I_T_I_E_S_ 5.
The RC700 PASCAL system is supplied with some utility programs,
which are not part of the standard UCSD PASCAL system. They are
described in this section.
5_._1_ _ _ _ _ _ _ _U_t_i_l_i_t_i_e_s_ _o_n_ _t_h_e_ _L_o_a_d_e_r_ _D_i_s_k_ 5.1
If you in response to the prompt 'INSERT PASCAL DISK - TYPE
<RETURN>' type <esc> instead of <return>, the system will reply
with the prompt 'PROGRAM?'.
You have three choises to answer this question:
1) 'PASCAL' returns to the PASCAL Loader.
2) 'FORMAT' prompts you with 'INSERT DISK - TYPE <RETURN>'. The
disk inserted is formatted according to the format given in
chapter 4.
NOTE: This is only relevant for MINI-diskettes. MAXI-diskettes
cannot be formatted in this way.
3) 'SYSTEM' generates a new load disk. It can also be generated
by copying the disk, but this is a faster way. Just insert a
disk, when the prompt 'INSERT DISK - TYPE <RETURN>' appears.

The backup program BACKUP.CODE copies a whole disk. It asks for
the source and destination unitnumbers for the transfer. The
program will work on both one and two drive systems.
\f
In dual drive systems the drives are named '#4' (drive 1) and
'#5' (drive 2), ref. 1, p8.
On a one drive system it is a little more tedious, as you have to
interchange the source and destination disks a number of times
(refer to app. D).
To execute the backup program, type X and BACKUP at the Command
level (the disk containing BACKUP.CODE must be on-line, refer to
chapter 7).

The system is distributed on two MAXI-diskettes or four
MINI-diskettes. The MAXI distribution set consists of one Pascal
loader diskette and one Pascal System diskette (volume id: SYS:).
The MINI distribution set consists of one Pascal loader diskette
and three Pascal System diskettes (volume id: SYS:, SYS1: and
SYS2:). The Pascal System load diskette (see chapter 2) is the
one marked SYS:.
The following is a list of the files on the distribution
diskettes with references to the appropriate documentation. The
files listed under volume id SYS1:, SYS2: are incorporated in
SYS: on the MAXI-diskette.

Notes:
Running the PASCAL compiler in a floating point configurated
system requires the existence of the following two files on SYS:
SYSTEM.LIBRARY and SYSTEM.LINKER
These files should be tranferred from SYS1: in case a
MINI-diskette system is used. In case a single drive system is
used, the user disk-space is approximately 18 blocks.

17) Now the execution has finished and you enter the
f_i_l_e_r_-_p_r_o_m_p_t_-_l_i_n_e_ (1) again. To return to the Command-level
type 'Q' (the c_o_m_m_a_n_d_-_p_r_o_m_p_t_-_l_i_n_e_ is displayed). Save your
master diskette. From now repeat the procedure starting with
point 2b) until you have generated all three copies (1 of 3, 2
of 3 and 3 of 3). Hereafter you may start to use the
PASCAL-system on your new diskettes.
