I have been performing some tests. There are a lot of variations: not just JCL but SVC 99, FTP, etc.
People here love to demonstrate their knowledge. What's wrong with asking them? Discussion of the city of Toronto's airports is okay but a discussion of PDS DISP= is not? The problem is not obvious, as you have seen in having re-thought your first answer.

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. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
