XPD ROUTINE UPDATE (238)    OPTION (19)

This option lets you update the Routine File by adding existing routine
names from the current system.  You enter the namespaces of routines to
update the routine file with, and namespaces to exclude from the updating. 
In addition, if you ask it to, this option goes through the Routine File
and deletes any local routine names that no longer exist on the system.
Any routine listed as national will not be removed from the file.
