IEC192I OPEN MACRO MAY HAVE BEEN USED WITH INCONSISTENT MODE SPECIFICATIONS.

Explanation
The first DCB address in the OPEN parameter list
is zero. This address value could be caused by specifying MODE=31
on the list form of the OPEN macro, and MODE=24 on the execute form.

System action
If this is a multiple-DCB invocation of OPEN,
the second DCB address should point to storage that belongs to the
user.  If it does, the job continues; otherwise, the job fails and
message IEC191I appears after this message.

Programmer response
If you generated the parameter list by using
the list form of the OPEN macro, change the mode specification to
be consistent on both the MF=L and MF=E forms of the OPEN macro. 
Otherwise, to have consistent modes, you may either change the form
of the parameter list or change the mode specification on the MF=E
form of the OPEN macro.
