A-Shell Reference

Added December 2022

xcall XRUNLOG, evt, jcbrec, status

Xrunlog.sbx enables customized activity tracking.It belongs to the special category of Hook subroutines which are really just defined interfaces allowing developers to plug in their own logic to customize or extend standard A-Shell behavior.

Parameters

evt  (Num)  [in]

Specifies the event:

Value

Event

1

Start of A-Shell session

2

End of A-Shell session

4

Start of RUN

8

End of RUN

 

jcbrec  (ST_JCBREC)  [in]

Contains a copy of the JOBTBL record for the current job. See ASHINC: JOBTBL.SDF in SOSLIB:[907,16].

status  (Signed Int)  [in/out]

Initially set to 0, this will contain the value passed back by the prior call to this SBX for this job. Provides a way for the SBX to link the start and end events together (by log file position, record number, key, etc.)

If Xrunlog.sbx is found in DSK0:[7,6] when A-Shell is launched, it will be called at the start and end of the A-Shell session, as well as at the start and end of each RUN. It is not called for LIT and SBX events.

The sample program XRUNLOG.BP in SOSLIB:[907,54] creates a simple sequential file log of the events. It is similar in concept to the ashlog.log file when the INOUT and EXEC TRACE flags are set, but more focused and consistent in structure. The sample subroutine also contains a function that processes the raw log, creating a consolidated version with just one entry per session or RUN with some elapsed activity counts.
