To CONWRITE or not to CONWRITE... THAT is the question! :)

[John Dueckman]

Here is a trivial practice question that I'm curious as to what the greater Endevor community might think....

Many processors are written so that one of the FIRST steps is to execute CONWRITE to fetch a copy of the source to be processed. 

Now the question:

Should you leave that step in if you are using unencrypted Reverse-Base-Delta and a PDS/PDSE as your base library? Or do you just go against the base library? 

I know what MY thoughts are but I'm curious about yours! :)

Hi John,
I am not a fan of redundancy, so if your Type definitions indicate REVERSE UNENCRYPTED settings, the CONWRITE would be redundant.  Using the &C1BASELIB symbolic for input would certainly replace the CONWRITE step.
 
However, if you are NOT 100% positive that ALL your types are REVERSE etc. then CONWRITE might be required.
 
So, the real answer would be "it depends"?

Hi John,
  I agree with Bernie if the Type definition has REVERSE UNENCRYPTED - eliminate the step. It simplifies the processor and reduces overhead - less steps, less temp data set management. I know the new machines are wicked fast but a nanosecond here and a nanosecond there....

We do .. lots of ++INCLUDE code leftover from panvalet.

Here's a scenario, what if you did use the &C1BASELIB and the member had been updated outside of Endevor?   

In the processor, I would assume it just would use that library member and go on but not 100% sure. 

If you were using CONWRITE to get a copy of the source from Endevor, I would assume that the step would have a condition code to advise you that the footprint had been compromised.  

Also with CONWRITE you could expand include modules with the source to pass to the next step. 

Sorry don't have time to set up a test for this, so just throwing out some "What IF"  questions.
