The only way a user is allowed access to the services
of the CAMPS System is through terminal positions.
A terminal position is one of the three equipment types
listed below:
1) VDU with keyboard and one to four medium speed
teleprinters
2) VDU with keyboard and one medium speed teleprinter
3) VDU with keyboard
Users may basically be considered to be one of the
following three kinds:
1) Supervisors
2) Supervisor assistants
3) All users not of kind 1 or 2 above in the following
denoted common users
Supervisors must access CAMPS services through terminal
positions of equipment type 1.
Supervisor assistants must access CAMPS services through
terminal positions of equipment type 2.
Users may access CAMPS services through terminal positions
of equipment types 2 or 3.
CAMPS services are separated into groups of services
denoted CAMPS functions.
The CAMPS functions are:
1) Supervisor Function (Supervisor)
2) Message Distribution Control Function (Supervisor
assistant)
3) Message Service Function (Supervisor assistant)
4) Preparation Function (common user)
5) Release Function (common user)
6) Reception Function (common user)
The CAMPS System holds for each terminal position a
terminal profile stating the CAMPS function which may
be accessed from that position and a list of operators
which may get access to CAMPS services through that
position.
For each user with access rights to CAMPS services
the system holds a user profile stating which function
the user may get access to.
4.4.1 H̲o̲w̲ ̲t̲o̲ ̲g̲e̲t̲ ̲A̲c̲c̲e̲s̲s̲ ̲t̲o̲ ̲C̲A̲M̲P̲S̲ ̲F̲u̲n̲c̲t̲i̲o̲n̲s̲
The first action a user may perform when wanting access
to CAMPS is to put the locking mechanism of the terminal
positions VDU in ON position. The system will now recognize
the terminal position as manned.
If the terminal position is equipped with a printer
the locking mechanism of the printer shall be put in
the ON position else the system will treat the terminal
position as not equipped with a printer.
After turning the locking mechanism to the ON state
CAMPS will await a sign-on by the user. During sign-on
the user shall enter his identification and his password.
If the user fails in sign-on three times the terminal
position will be blocked, i.e. no further sign-on attempt
will be allowed, and a warning is sent to the supervisor
position. The only way a blocked terminal position
can be unblocked is by a supervisor command.
After a successful sign-on, i.e. entry of correct operator-id
and password, a menu will be displayed to the user
informing him about the services to which he has got
access.
For examples of menus refer fig. 4.4.1-1 and fig. 4.4.1-2.

4.4.2 U̲s̲e̲ ̲o̲f̲ ̲V̲D̲U̲
a) The VDU screen is divided into two areas; a five
line VDU header and a 22 line format area. The
header contains terminal status information and
the format area is used by the system to display
formats and by the user to enter data. Refer fig.
4.4.2-1 and fig. 4.4.2-2.
1) V̲D̲U̲ ̲H̲e̲a̲d̲e̲r̲ ̲A̲r̲e̲a̲
- Terminal Function, i.e. transaction in
course
- Classification of current screen contents
- Time (Day, hour, minute, zone, month, year)
- Queue status
- Command line (for entry of commands)
- Response line (for display of e.g. error
messages)
2) F̲o̲r̲m̲a̲t̲ ̲A̲r̲e̲a̲
The format area is divided into the margin
area and the user area.
3) The margin area consists of the left-most ten
characters column on the screen and is used
by the system to indicate errors and line type.

The user area consists of the right-most 70
character columns on the screen.

4) The user area serves two purposes:
1) Display of information queued for the terminal
position
2) User input of information to be entered
into CAMPS.
5) When a user wants the next piece of information
queued for his terminal position to be presented
for him he enters the NEXT MESSAGE command.
The user will then control the presentation
of the information using the
- Page-on
- Page-back
- Scroll on
- Scroll down
function keys as available on the actual VDU.
If a printer is part of the configuration of
the terminal position the common user may use
the print command to get a hard copy of the
information currently presented at the VDU
screen.
6) When the user wants to prepare information
with guidance of the system he enters the command
appropriate to the type of information he wants
to prepare.
The system will then, in the user area of the
screen, display a format consisting of protected
field descriptions, and unprotected fields
into which the user may insert the actual value
of the field parameter. With each data entry
field is associated a one-character "field-descriptor"
informing the user of the type of parameter
to be entered alpha, numeric, or alphanumeric,
and whether the parameter is mandatory or optional.
In fig. 4.4.2-1 the symbols used in VDU layout
formats are shown and in fig. 4.4.2-3 an example
of a screen lay-out is depicted.

Format Display Example
When the format is displayed for the user the
cursor will be positioned at the first character
in the first data entry field.
The user may control the cursor position using
the next field function key moving the cursor
to the first character of the next data entry
field, the previous field function key moving
the cursor to the first character and the cursor
up, down, right, left keys.
If the user needs more format lines, he may
request these by issuing the the insert N lines
command. Lines which can be repeated are marked
by R in the margin area. (Refer fig. 4.4.2-1
lines 7 and 8). Such lines may be deleted again
using the delete N lines command.
Editing is performed by overwriting the old
contents in the data entry fields.
When the user has entered all information needed
he enters the information to the system, be
depressing the transmit function key. The system
then validates the entered information and
if any errors are found the entry-fields in
error are indicated and an error number shown
in the margin area.
If the user wants a full display of the error
message instead of the number, he achieves
this by entering the proper command in the
command line.
For detailed information refer ICD/001 and
ICD/002.
4.4.3 U̲s̲e̲ ̲o̲f̲ ̲P̲r̲i̲n̲t̲e̲r̲s̲
a) The printers (one to four) associated with the
supervisor position works in parallel with the
Supervisor VDU i.e. printers are printing independently
of supervisor VDU activities.
Four types of supervisor print out has been defined
each assigned a priority used when more than one
print out type is to be printed at one printer.
Assignment of print out types to the Supervisor
printers are controlled by the supervisor using
the appropriate commands.
For details refer CPS/210/SYS/0001. Print lay-out
for supervisor print types refer CPS/230/ICD/002.
b) Supervisor assistant printers refer CPS/210/SYS/0001.
Print lay-out refer CPS/230/ICD/002.
c) If a printer is part of the equipment configuration
of a terminal position for a common user, the user
may command a hard copy of the information to be
printed.
For details refer CPS/210/SYS/0001 and CPS/230/ICD/0001.
Print lay out refer CPS/230/ICD/0001.
4.4.4 U̲s̲e̲ ̲o̲f̲ ̲S̲u̲p̲e̲r̲v̲i̲s̲o̲r̲ ̲V̲D̲U̲
The use of the Supervisor VDU is as described in section
4.4.2 with the following exception.
Only one supervisor VDU is active at one time. The
active supervisor VDU will be the one where the ASSIGN
command was issued last.
