Re: [IBMiOSS] Checking return status of Pyhon program

So, you're building a file with the data retrieved? Maybe just retrieve it
to a temp file name and then change the name when you have it completely
downloaded. CL program can then check for the real name to see if it
exists, if it does then you know the download completed fully.

Not ideal, but should work.

That's the problem - getting feedback to the CL. For example, if I get a
partial download I can't continue. I can easily check for no download but
need to handle the other cases.

Environment variables don't work since it's a separate job.

I guess I could create a "success" temp file upon a fully successful
completion and test that in Cl. Seems kind of crude.

I'd probably use the logging module to log everything that happens in the
Python program. Doesn't give your calling CL any good info, but it will
let you analyze after the fact to see if it was successful or not...

I have a CL driver that calls a Python program to retrieve data via a
webservice.

CALL PGM(QP2SHELL) PARM('/QOpenSys/usr/bin/python3'
'/NYSLA/YMAR701.py')

I'm not seeing an obvious way to validate if the Python program ran
successfully. It has try/on exception blocks so it won't blow up.

For example, I made a slight change and had an indentation error.

Obvious

Python failure but how can I inform the CL?

Doing a RCVMSG *LAST, I don't see any message "call QP2SHELL ......" like
I see with "call QSH ......".

I see some documentation that IBM recommends calling QSH and invoking

PASE

thru that.

Suggestions? Does anyone have an example of using the QSH method and
error checking that they could share?

Thanks.
