True rather than right.
I hadda lookitup. In the JCL Ref.:
Rules for coding symbols in JCL
Follow these rules when coding symbols in JCL:
...
4. Do not use symbols to change the identifier field, name field, or
operation field of a JCL statement.
JCL specification was written by the infinite number of monkeys
who didn't grasp orthogonality.
Even worse are the rules for overrides and referbacks to nested
PROC calls. I recognize that immutable structure of control blocks
allows for only two levels. The restriction could have been eased
by generated procprocstep names.
