Just "for fun", I'm testing weird JCL things. A couple of things that
I've found that are weird are:
1) If you do something like:
//OPROC PROC
//IPROC PROC
//STEP2 EXEC PGM=IEFBR14
// PEND
// PEND
//XSTEP EXEC PROC=OPROC
//RSTEP EXEC PGM=IEFBR14
You will get a JCL error. But the JCL error is on the second PEND
statement. Nothing is said about not having a PROC defined within a PROC
in this case. But if you then remove the one of the PEND statements, the
error is when OPROC is expanded with a message "PROC VERB STATEMENT OUT
OF SEQUENCE"? If you don't expand OPROC, then you get no error message
at all!
2) You can do this:
//MYPROC PROC
//STEP1 EXEC PGM=IEFBR14
//SYSIN DD *
XXX
// PEND
//OSTEP EXEC PROC=MYPROC
The JCL error occurs in the expansion on the OSTEP step with "IEFC601I
INVALID JCL STATEMENT". Again, if you don't try to expand MYPROC, then
you don't get an error.
Somehow, this just seems wrong to me. Of course, I don't know the
history of the JCL converter / interpreter either.
This all came up in my testing of my JCL parsing routine. Yes, I'm still
doing it despite some rather negative comments from others about it. In
the 0.0000000001% chance that anybody cares, I have gotten all the JCL
so that each logical JCL statement has been composed from the physical
statements (i.e. concatenated the information from multiple
continuations and removed all comments). Not too bad, considering the
amount of time that I've worked on it.
