New Features of MPE/iX: Using the Hierarchical File System

UDCs, JCL, Command Files, and Programs 

Existing UDCs, JCL, command files, and programs function on MPE/iX as
they do on MPE XL. By default, existing MPE XL commands and intrinsics
take MPE syntax rather than HFS syntax.

MPE/iX also provides several useful UDCs listed in the section
called "System-Provided UDCs" in Chapter 2.  These are located in
HPPXUDC.PUB.SYS. You need to activate these UDCs using SETCATALOG as you
would other UDCs.

For example, to activate the UDCs system-wide without overriding any
other UDCs you have set up:

     :SETCATALOG HPPXUDC.PUB.SYS; SYSTEM; APPEND 

You must have SM capability to use this command.


NOTE  If applying the HPPXUDC.PUB.SYS catalog, realize that there may be
      an impact on third-party UDCs.
