By that logic, every program should always return a zero. If I code
LR 16,1
then the assembler will generate a halfword of zeros, because there is no
register 16. The assembler always generates zeros for invalid instructions.
Thus the assembler has done exactly what I told it to do. Nonetheless, it will
give me an RC 8 or 12.
Yes, I read that section of the manual. IBM clearly does not promise anything
in particular in the way of return codes, so it is certainly possible to argue
that the 0 is correct.
Nonetheless it utterly violates the principle of least astonishment.

IIRC, you stated earlier that you received messages similar to this one:
IGW01557W MEMBER FOO NOT COPIED BECAUSE THE NAME ALREADY EXISTS IN
THE OUTPUT DATASET CAUSING A COPY GROUP NO-REPLACE CONFLICT
That would indicate to me that you did not specify Replace (R) on either the
INDD parm of COPYGROUP/COPYGRP or on the SELECT statement for the members.
Since the specified members already existed in the output file and you did not
specify Replace, then you told IEBCOPY to only Copy the members if they did not
exist in the output file. IEBCOPY did exactly what you told it to do, so the
Return Code should be zero! Oddly enough, if you specify Replace and you Copy
a member that does not exist in the output file, IEBCOPY will give you a Return
Code of 4! :-)>
IEBCOPY and other utilities Return Codes are documented, (somewhat!), in
"Appendix A. Invoking Utility Programs from an Application Program" in the
"DFSMSdfp Utilities" manual, (at least in z/OS V2.2).
