Checking for undefined macros

[Peter Boks]

Normally all macro execution stops by calling an undefined macro. Does anybody know a way to check if a macro exists? This check should be done from within a macro, without stopping it if the macro it searches for is undefined.

The formatting is probably shot: DEFINE MACRO_TEST LOCAL MACRO_NAME LOCAL C LOCAL E READ MACRO "Enter macro name" MACRO_NAME TRAP_ERROR MACRO_NAME LET E (ERROR_STR) LET C (CHECK_ERROR) IF (POS E "not defined") DISPLAY E ELSE DISPLAY ("The macro: "+MACRO_NAME+" is defined.") END_IF END_DEFINE

[Frederic LHOTE]

Darren's macro is fine but you are obliged to run the macro you want to test. You can also make a LIST_MACRO_NAMES 'your_file.txt' and search for your macro is this file.
