This document describes the function of the DRP Subsystem.
1.1 I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
The purpose of the DRP Subsystem is to display the
routing table and to support the operator in changing
the delay table for generating a new routing table.

3.1 F̲U̲N̲C̲T̲I̲O̲N̲A̲L̲ ̲C̲A̲P̲A̲B̲I̲L̲I̲T̲I̲E̲S̲
3.1.1 D̲R̲P̲ ̲M̲a̲i̲n̲
The DRP process will be activated when one of the two
following commands:
DDU
DRT
are entered at one of the terminals at the SCC.
When the DDU command is entered the delay table will
be displayed and the operator will be guided in changing
the table. After changing, a new routing table is
generated and displayed for accept. If the operator
accepts this new routing table it will be released
as the new routing table, else it will be deleted.
When the DRT command is entered the routing table will
be displayed.
When the command is processed a log will be made.
This log will include the command, where and when.
3.1.2 M̲T̲C̲B̲M̲I̲N̲I̲T̲
The MTCBMINIT procedure gets the file descriptors for
the system volumes (MOVHEAD and FIXHEAD) and initiates
the MTCB Monitor.
3.1.3 G̲E̲T̲C̲M̲D̲
In the GETCMD procedure the DRP process will wait for
an operator command.
3.1.4 I̲N̲I̲T̲ ̲F̲R̲D̲ ̲V̲D̲U̲
The INIT ̲FRD ̲VDU procedure will display the delay table
on the VDU.
The format will be:
DELAY TO:…02…A: B: . . Q:
F̲R̲O̲M̲:̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲
A: 010 010 . . 010
B: 200 010 . . 010
. . . . . .
. . . . . .
Q: 010 005 . . 010
The numbers will be delay values e.g. the delay value
from A to B will be 10 items.
3.1.5 V̲D̲U̲I̲O̲
The VDUIO procedure is used to input and output data
from and to the VDU.
3.1.6 G̲E̲N̲ ̲F̲R̲T̲ ̲T̲A̲B̲L̲E̲
The GEN ̲FRT ̲TABLE procedure will display the routing
table on the VDU.
The format will be:
ROUTE TO:…02…A: B: . . Q:
F̲R̲O̲M̲:̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲P̲S̲T̲ ̲ ̲ ̲ ̲ ̲P̲S̲T̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲P̲S̲T̲
A: --- BN- . . KN-
B: AN- --- . . ANL
. . . . . .
. . . . . .
Q: K-- K-- . . ---
This means that if B has to send a message to A, first
it will try to send it directly to A. If B cannot
do this it will try to send it via N.
3.1.7 I̲N̲S̲E̲R̲T̲ ̲M̲T̲C̲B̲
The INSERT ̲MTCB procedure creates a MTCB and updates
it with the content of a buffer.
3.1.8 I̲N̲S̲E̲R̲T̲ ̲Q̲E̲
The INSERT ̲QE procedure inserts a queue element into
a specified queue.
Usecount of the MTCB referenced by the queue is unchanged.
3.1.9 D̲I̲S̲P̲L̲A̲Y̲ ̲E̲R̲R̲
The DISPLAY ̲ERR procedure will display error codes
to the operator in case of Syntax- or semantic errors.
The error code will be displayed on the last line
but 3.
