Edit macro names can be any valid CLIST, REXX, or program name. Using the DEFINE ALIAS command, you can assign command names for running the edit macros that are different from the actual name.

When choosing names and aliases, avoid defining names that might conflict with the DEFINE command operands and their abbreviations. You can do this by implicitly defining the macros: precede program macros with an exclamation point (!); do not use explicit definitions for CLIST or REXX macros.
