Don't forget to write a program to clear the data area for when the batch
job fails.

I like to create the data area, have the batch job do an ALCOBJ *EXCL, then
when it ends the object is released.

The interactive program can try to do the ALCOBJ too, and if it receives
CPF1002 it retries.

Subject: Technique critique?

This is more of a CL programming question:

Background: I have an interactive program that I need to have NOT run
while a specific batch job is running. Currently the batch job updates a
data area with a flag at the start of the job and then clears it at the
end. Interactive jobs can then check for this flag before running.

I have this code in my CL:

CHECK:
/* Check data area to see if job is running */ Rtvdtaara DataArea
rtnvar(&Check) If (&Check = '1') then( DO )

/* wait 30 seconds and then try again */ Dlyjob dly(30)
Goto CHECK
ENDDO


The GOTO is bothering me, so the question is - would you code this
different? This seems simple and straight-forward, but in your opinion is
there a better way?

Thanks
