Can you execute a PROC from another PROC?

Thanks

Yes, you can, up to 15 levels.

As Mervyn has put it - upto 15 levels of nesting is allowed.

But it would be a nightmare when a proc has too many nestings particularly when we have ddname overrides in a JCL. One has to code all the proc stepnames (such as //PSTEP10.P1STEP10.P2STEP10...) for the ddname override. Also it may become quite complex when we have to use condition codes. I would not prefer nested procs. At present Iam unable to think of other situations where it would lead to complications.
