That's SYSIN DD DUMMY, not SYSUT1 DD DUMMY.

Actually, "SYSUT1 DD DUMMY" simplifies things a bit.
It really speeds up the processing time. :-)
Right :-) To clarify, I assumed the reference to DUMMY was
about control statements. If SYSIN has control statements,
ICEGENER assumes they're for IEBGENER and uses IEBGENER to
process them. If SYSIN DD DUMMY is specified, there are no
IEBGENER control statements, so ICEGENER can use DFSORT copy.
(Control statements for DFSORT copy, like INCLUDE, can be
specified with DFSPARM.)
And I might mention that DUMMY is __required__. We had some jobs that
ran with SYSIN being a DD *, but with no control cards. This is,
technically, equivalent to DUMMY, but not by ICEGENER. The same applies
to an "empty" dataset with no control cards. Just mentioning this
because it bit us once.
Well, that's not just for sorts and utilities;
A DD * with no lines is _not_ the same as DD DUMMY.
There are differences in allocation, for example.
