30 years ago I wrote something that ATTACHed multiple TCBs, each calling ICEMAN. This worked fine but I needed to
1) Create the control cards appropriately 2) Make sure there weren't any data set collisions In fact my use case was read the same SORTIN and sort it different ways - in parallel. Oh... 3) Manage the virtual and real memory appropriately. So, yes, I think multiple tasks invoking ICEMAN in a single job step can be done.

There is a possibility that more than one task might need to call sort. Will this cause a problem if one task calls sort while sort is active for another task? A customer could be using any of the available sort products. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
