Substitution variables in procedures

You can use QMF substitution variables in linear procedures and procedures with logic.

A substitution variable is any variable that you can use in a QMF command; QMF manages these variables for you. A substitution variable is always preceded by an ampersand (&). You can assign a value to a substitution variable by setting global variables, by specifying values on the RUN command, or by specifying values on the RUN command prompt panel. For information on setting global variables, see SET GLOBAL.
