UNIT=INTRDR is not valid in JES2, and the internal reader is very much alive 
and well. It does not present a security issue, and bog standard users can 
exploit it freely.

HASP made it easier; if you allocated an output data set as UNIT=INTRDR,
whatever was written to it would get read as input to HASP (that is, if it
started with a //    JOB  card, it would be treated as a batch job).  I
believe that was carried into JES2, as well, but for security reasons, it
isn't used that way any more.
