Hi,
what symbol must appear in the beginning of an instream procedure statement to make sure that the statement is not overridden?

Hi,
i want a particular statement within an instream procedure to be avoided from being overridden, not the entire procedure.

you could nest the procedure. I that makes it hard if not impossible to override.
otherwise, I don't see how to prevent someone from using proper JCL syntax to override something, especially in an instream procedure.

Dbz is correct, you can only code overrides one level down so nesting procedures would work. But if they're both instream there's nothing from keeping a clever JCL user from overriding the nested procedure from the instream procedure. From "Modifying Nest Procedures" chap 5 of the JCL reference:

Quote:
Modifying or additional JCL statements apply to one level of nesting only. You
can use statements to modify statements in a procedure only for the level of
nesting at which the EXEC statement for that procedure appears.
