IIRC, once you go to LARGEDS format on *ANY* spool volume you cannot go back (LARGEDS=FAIL) except via a cold start.
Can't think of anything else to worry about. HTH, <snip> z/OS V1.9 I am getting ready to move my spool from MOD3 to MOD9. I think the only thing I have to do is change the spooldef to LARGEDS=ALLOWED or ALWAYS and then Allocate/$Snewspol/$Zoldspol Is there anything else I need to worry about or review? </snip> ---------------------------------------------------------------------- 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
