04.02 Function of the Commercial Translator Supervisor - CTM

The primary function of CTM is to provide continuous automatic operation upon a sequence of (stacked) Commercial Translator Processor jobs. This supervisor gains control from the Basic Monitor as the result of a Basic Monitor Control card of the form:

$EXECUTE         CT

CTM then controls the processing of the input on SYSIN until the Basic Monitor control card

$IBSYS

is encountered, at which time return is made to the Basic Monitor.

The format of that part of SYSIN which is concerned with Commercial Translator Processing is as follows:

$EXECUTE          CT
     CTM Control Card for JOB1
     JOB1
     End-of-file
     CTM Control Card for JOB2
     JOB2
     End-of-file
     Input for JOB2
     End-of-file
     .
     .
     Etc.
     .
     .
$IBSYS

Note — Each Commercial Translator job must be followed by an end-of-file. (See 05.03)

In accomplishing automatic operation upon a stacked job input-tape, CTM performs the following functions:

1. CTM reads control cards for subsystem branching.
2. CTM provides communication, transfer, and return points for CTM subsystems.
3. CTM provides system tape positioning and reading of CTM subsystems and IOCS packages.
4. CTM provides for switching of the Basic Monitor Unit Function Table entries for SYSOU's, SYSIN's, and SYSPP's when any CTM subsystem causes reel switching of the corresponding table entries.
