Yes, it would, but how would you get 100% compliance wiht no mistakes from 

A 360 s'posedly COULD be told to ignore, or to respond to something else, 
but that wasn't usually available.
Accordinglyly, when we needed to use a 360 to duplicate a deck that had 
JCL cards, we would turn the source/data deck upside down.  (hope that it 
didn't have '/' in column 80?)
