Are you perhaps referring to 'deferred substitution" using the
ampersand "&" character?

See e.g. an OpenVMS Users Manual for your VMS of choice, and its 
section on Understanding Symbol Substitution.

E.g.

If you provide an actual (rather than vague) example of what
you're looking for, the answer may become clearer.
