Not to worry. The way the board is setup, members cannot edit their posts once submitted. There is a Preview capability so you can look at your post as the forum will see it before you click Submit.
i don't understand the UNIT=xxxxx, part tho
When creating a new dataset, you specify which unit type to use for the dataset. Some are SYSDA, 3390, DISK, CART, TAPE, etc). You would learn which UNIT= is proper for your system by your peers, your manager or the system support people. A partitioned dataset must be allocated on a direct access volume, not sequential media (like a tape).
//SYSUT1 DD DISP= ... ???
Your requirement said the data to go into the member was to be "in stream". This would be a DD * with the data for the member in the following line(s).
Member names are bound by () as i posted before.
I suggest you invest the time to understand the EXEC and DD staements. You might look at the JCL manual, but spending time with people already using the same system you use would be more helpful. A forum is not a way to learn jcl from scratch.
