interactive?  as in interfacing to a user?  sure:  if the executing
program does some computation, it can issue a DYNALLOC (SVC 99) to
allocate the appropriate IO device, such as a terminal.

further, it could use the INTRDR facility to submit job steps according
to conditions.

but is this the right way to do things?  why does it have to be run
under JCL and not TSO, or even CMS?  jcl is painful.
