I doubt it. Changing the default only allows you to create a PDSE that supports generations up to the limit that you set. In order to be able to use member generations in a PDSE, you first have to define it as a Version 2 PDSE with some number of generations. I've only done that on an ISPF 3.2 panel, but you can do it in JCL too. Having created the PDSE, any time you write an existing member, it creates a new generation by default. You can use SAVE NOGEN in the ISPF editor to overlay the most current generation instead. You can open a previous generation in Edit or View by specifying the generation that you want. That's done by entering a / in the prompt field and specifying which generation you want to use. One thing that confused me a bit was that when I opened a generation other than the current one for edit, then saved it with SAVE NOGEN, the old generation was updated. I had expected that it would update the 0 generation. If you open a prior generation and save it without NOGEN, a new generation is created that becomes the most current. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
