Because the SCLM editor uses ISPF edit macros to perform its functions, you should not override SCLM command macro definitions, especially the END, SAVE, CANCEL, and RETURN macros. If you need a user-defined "end" macro, use another command name such as QUIT. At the end of this alternate end macro, invoke the END, RETURN, SAVE, or CANCEL command to start the SCLM end routines.

If you override an SCLM macro by using DEFINE, the macro is not redefined until you begin a new edit session.

You can also override SCLM edit macros by entering the ISPF BUILTIN command (for example, BUILTIN SAVE).
