Here is what the JCL manual z/OS MVS JCL Reference SA23-1385-00 Location in
the JCL states:
A SET statement can appear anywhere in the job after the JOB statement with the
following restrictions:
It must appear in the job's JCL before the intended use of the symbolic
parameter.
It must follow a complete JCL statement.
It cannot appear immediately after the first DD statement within a
concatenation.
Examples: The following JCL will work.
//DD1 DD DSN=dsnA,DISP=SHR
// DD DSN=dsnB,DISP=SHR
// SET
// DD DSN=dsnC,DISP=SHR
The following JCL will fail.
//DD1 DD DSN=dsnA,DISP=SHR
// SET
// DD DSN=dsnB,DISP=SHR
// DD DSN=dsnC,DISP=SHR
The way I read it, the FIRST DD statement in a concatenation cannot have a SET
following. But the next one can.
So in your JCL you seem to have a concatenation of
//DD2 DD *
// DD PATH='/dev/./null'
According to the text above, you would have to put the SET after the DD PATH or
before the DD * but not immediately after the DD * statement.
I would expect this to work:
// SET
//DD2 DD *
// DD PATH='/dev/./null'
I would also expect this to work:
//DD2 DD *
// DD PATH='/dev/./null'
// SET
// DD DISP=SHR,...
I would NOT expect this to work:
//DD2 DD *
// SET
// DD PATH='/dev/./null'
Though I could be wrong. Sometimes IBM documentation is misleading. To me the
behavior is along the lines of this documentation. To verify, you could change
the DD * to a dataset and see if it still fails.
