 1 Package Description (this docu-
 ment)

Requirements
SW2114 requires:
 MS-DOS 3.3 (SW954001) rel. 1.0
 or later
or
 Concurrent DOS vers. 6.0 or later 

The system may run under UNIX
VP/ix too.

Installation
The installation of SW2114 is perfor-
med by inserting the diskette in a
drive, selecting that drive and
typing:-   

     INST

This batch job will provide a guide to
installation of the files on the disc
onto a specific drive.

The compiler will be installed in a
directory called RTP.

To be able to call the compiler from
all directories the path RTP must be
included in the searchpath of      the
operating system. This may be done
by adding RTP as parameter to the
PATH command in the AUTOEXEC.-
BAT file ( for CDOS: the STARTxyy.-
BAT file ).


Changes since last release
The extension of the objectfile is
changed from .T35 to  .T22

Changes and corrections since relea-
se 2.6

-          Error in connection with index into
           a string, rule066a.
-          Error in code when loading add-
           ress of a field of a type set.
-          Error in code in assign when no
           rangecheck ( TA).
-          Error in get_argument.
-          Error in connection with dynamic
           records with types of length 0.
-          Error in connection with IN.
-          Error in megaload when adding
           offset to addr when size = 2, 3    
            for arrays (3502).
-          Error when using pred and succ.
-          Error when initialize array of array
           with dynamic size.

Changes since release 2.5

The predefined switches: compiler,
RC5000, and PI3 have been replaced
by: language, TA, and I86.

The following bugs have been cor-
rected since release 2.4:

-          Error in connection with local re-
           ference in a forward declared
           routine
-          Error in the object code in connec-
           tion with empty case statement
-          Error in the object code when
           using packed fields as value para-
           meters



Known Problems
Option CREATESIZE puts the crea-
tesize in inner programs if any.

Wrong code when using routines
with formal value parameter of
a bound string type.

Bound string type:
When a formal value parameter is of
a bound string type (e.g. alfa), the
actual parameter has to be string of
the same length, because the actual
parameter is not converted to a
string of the same length as the
formal parameter.

RC5000 MegaSwitch as target com-
puter
-          Structured values of type packed
           array and packed record are not
           implemented.
-          packed3502 is only implemented
           for types where the components
           are either not crossing a byte
           boundary or are of type INT16

Intel x86 as target computer
-          packed3502 is only implemented
           for types where the components
           are either not crossing a byte
           boundary or are of type integer


RC5000 Network Switch (RC3502)
as target computer
-          Structured values are not imple-
           mented
-          Use of RC3502 interrupt handling
           is not supported ( i.e. CHANNEL
           statements )
-          Structured constant as array limits
           is not implemented correct.
-          Succ on a subrange, which limits
           are given as process parameters
           does not work correct.
-          LOCKDATA of dynamic types
           with packed array of bit are not
           packed.
-          There is no cleanup when exiting
           routines with local declared re-
           ferences and external specifica-
           tions.
-          Rangecheck is not performed at
           v:= v + 1; when v is a subrange.
-          Pointer type to the type itself is
           not allowed.


Release Notes
Memory Requirements for RTP

     Code                        143     K bytes
     Data                         31     -
     Stack                        10     -
     Heap                         60     -
     -------------------------------
     Total                       244     K bytes

Above figures are fixed except the
heapsize, which depends on the
program compiled.

The heap used for the internal name
and symbol table is not included in
the above figures.  Per default the
name and symbol table will occupy
all available heap (except the above
60 Kbytes) if needed. Note it is
possible for the user to specify the
maximum amount of heap the name
and symbol table may occupy.
