Isn't it the same thing? AFAIK, null and "-0-" are one and the same.

Chitiea Sent: Sunday, December 06, 2015 5:01 PM To: [email protected] Subject: [RBASE-L] - RE: IFEXISTS Arg3 "Equals Nothing" Javier: Must be a slow Sunday at the Valencia homestead. Same here. So here goes: SET VAR vNothing TEXT = NULL SET VAR vHumpty TEXT = NULL SET VAR vHumpty = (IFEXISTS(.vNothing,'Nothing Exists',.vNothing)) SHOW VAR vHumpty RETURN Returns the current NULL string: '-0-'. I'm going with Razzak's suggestion. Cheers!

(IFEXISTS(TextArg1,TextArg2, TextArg1)) Just a thought and I have not tested it...

(IFEXISTS(TextArg1,TextArg2, ??? )) (IFEXISTS(TextArg1,TextArg2, ' ' )) --<Space> ...introduces an unwanted <space>. TRIM cannot be applied in my specific circumstance. (IFEXISTS(TextArg1,TextArg2, '' )) --No <space> ...produces error message 2155: "The first and last two arguments for IFEXISTS must be the same type." Can't say I've ever asked R:BASE to do nothing.
