How on earth can IBM make a change as significant as this and not even document
the change in behavior? I can imagine this affecting many job streams with
negative consequences.

ERROR DESCRIPTION:
When DD statements within a procedure are overridden with
instream data (DD * or DD DATA), the data within the data sets
represented by those input stream DD statements may be swapped
(exchanged) if the overriding DDs are not in the correct order;
that is, in the order in which the overridden stmts appear in
the procedure.
This can happen because the MVS Converter may reverse the
sequence of two or more instream DD stmts with respect to each
other, but the data within the files referenced by those DD
stmts does not move along with the DD stmts themselves.
Running the same JCL in R707, the out of sequence instream
DD statements were simply ignored.
This issue was previously reported in OA05951, which was
closed SUG.
Additional Symptoms:
IEF655I INVALID DSNAME SPECIFIED WHEN SYSIN OR SYSOUT
SPECIFIED (msgIEF655I)
May occur if a SYSIN DD * statement is GENERATED and now
properly finds and overrides a SYSIN DD DSN= statement.
Additional Keywords:
SYSIN reversed reversal, asterisk, instream
