Hi Shmuel AMV"SH,
My experience has been that when the OPEN fails (e.g. missing/incorrect
ALLOCATion), the program gets an x13 ABEND and does not get as far as
checking DCBxxxxx.
Regards,
David

As Tom M mentioned, there are "commonly" encountered general situations.
It seems the same question would apply to almost any error encountered;
Operation exception is probably one of the easier ones to diagnose in many
cases.
Some of the "commonly" would be
* Wild branch to uninitialized storage at which the data is not a valid
instruction
* Branch to 0 because of an uninitialized pointer, at which the data is
not normally a valid instruction
* Use of an instruction that is not valid on the machine on which your
program is running
