As of Release 4.5 and 5.0, the operational components of MPE appear unchanged from a system management perspective. Existing UDCs, command files, and programs function identically on MPE/iX as they do on earlier releases.
However, if you plan to create files and directories using HFS syntax, you should review any UDCs and file equations that you have set up to be sure that they will not conflict with HFS syntax. For example, if name qualification is performed by a UDC or CI script, be sure that longer names (if used) will be acceptable in the commands.
