PLTPI

The PLTPI system initialization parameter specifies the suffix for, or the full name of, a program list table that contains a list of programs to be run in the final stages of system initialization.

PLTPI={NO|name|YES}
If NO is specified, no program list table is used.
If name is one or two characters (and not NO), the characters are suffixed at the end of the DFHPLT prefix.
If name is three to eight characters in length (and not YES), it specifies the full name of the program list table.
If YES is specified, a table called DFHPLT (without any suffix) is used.
For information about coding the macros for the program list table, see Program list table (PLT).
For information about writing initialization programs, see Writing initialization programs. You can use the INITPARM system initialization parameter to pass parameters to those programs.
