RE: Regarding DBGVIEW(*STMT) in CRTBNRPG

Hello Joep,

Yes, I choose for full optimizing because of size and to increase
performance. I know, the performance goal is very little, but I strive
to always deliver optimized code, with error catching in it, and without
source in it.
If program errors occur in production environment, I have to take the
program back in maintenance and do work on it until the code is correct.

Most code has error catching routines, it's not often that a user runs
into an error on which I have to hook in "live".
So for myself I don't want extra overhead added to my programs that I
won't use.
For others: I was just curious what their reasons were.

Best regards,
Arco Simonse
