Both JES2 and JES3 have alternative PROC sources. Worst case is a started job 
with a JCLLIB DD.

A job card for a started task is normally found in one of the data sets
pointed to by the IEFPDSI DD or the IEFJOBS DD of your Master JCL. Master
JCL is normally found in SYS1.PARMLIB or one of the data sets in your
PARMLIB concatenation in a member named MSTJCL00 or some other number other
than 00.
