What is the difference between DISP=NEW and DISP=MOD for a PDS member
(member name specified on the DD statement)?

Both disallow duplicate member names. Are there any differences? What?

DISP is always for dataset, not for member.
DISP=MOD for existing member ends with SB14.
DISP=NEW for existing member ends with JCL ERROR (assumed SMS).
DISP=MOD for non-existing member but existing PDS ends with "pds gas".

BTW: I'd suggest you to simply perform some tests - IMHO it's much
better than asking others about it.




Errata!

> DISP=NEW for existing *DATASET* (was: member) ends with JCL ERROR (assumed SMS).


To complement:
DISP=NEW for existing member means existing dataset, means ...see above
DISP=NEW for non-existing member, but existing dataset also ends with JCL ERROR.
