I think that they are more likely to be noticed. My own weird preference is to ABEND the program with a documented abend code which is unique for each possible critical error condition. I'd use the CEE3AB2 Language Environment subroutine. That way, I can have both an abend code and a reason code. As an example, suppose a file doesn't successfully open? I would abend with a code which indicated which file had a problem and a reason code which was the FILE STATUS for that operation. The only thing that I cannot get out of this is the FILE STATUS 2 codes for VSAM, which are very useful. However, they should be in the CEEDUMP produced by the CEE3AB2 routine.
