I recently had to put together a small program with JCL for work, and had real difficulty in finding documentation. Can you recommend anything?

Most of what I've learned has been from examples from co-workers, but I've also used the IBM knowledge center and the IBM "Redbooks".

I think the Redbook titled z/OS Basics has some JCL examples and exercises in it.

I also found this through a quick search: http://www.ibm.com/support/knowledgecenter/zosbasics/com.ibm...
