Command Replacements NonStop NET/MASTER MS commands can be replaced with an NCL procedure of
the same name. For example, at your site, the NonStop NET/MASTER MS
SHUTDOWN command may be replaced with an NCL procedure called SHUTDOWN
that includes a timer command to warn users at 1-minute intervals that shutdown is
imminent. (Command replacements are created with the SYSPARMS CMDREPL
command, usually by your system manager.)
You can display all the NonStop NET/MASTER MS commands that have been
replaced by NCL procedures of the same name with the SHOW PRELOAD command.
Replaced commands are displayed as type CMDREPL.
Two prominent examples of system-wide command replacements are the OPSYS and
PROGRUN commands. OPSYS and PROGRUN commands are used to access
Guardian utilities and other applications external to NonStop NET/MASTER MS. By
default, the “native” NonStop NET/MASTER MS OPSYS and PROGRUN commands
are replaced by NCL procedures by the same name that include extra security
checking and other enhancements. (OPSYS and PROGRUN are described in detail in
Section 7, “Accessing External Utilities and Applications.”)
