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.
