Extensions to &CALL

The SUBSYS command lets you nominate a subsystem as a complete &CALL replacement. This means that any existing NCL procedures that have used &CALL to call a program, for example, X, can be automatically redirected to a SUBSYS defined as X. This command is one way to gain immediate improvements in performance for some programs.

Note: For more information about the &CALL verb, see the Network Control Language Reference Guide.
