When submitting a job with JCL like
//jobname JOB ,'XXX ',MSGCLASS=H,
// CLASS=0,REGION=0M,
// RESTART=stepname
// ...
is there any place in the control block chains (PSA->TCB->TCT-> ... or PSA->TCB->JSCB-> ... or something else) where I can find info on, if the RESTART parameter was explicitly stated on the JOB-card?
