From: Espen on 10 May 2010 05:21 I'm constructing a macro where I want a macro-variable in a text string, but the macro does not recognize it. It looks like this: %macro test (var); (...) if effect ne '&var.constant' then delete; (...) %mend; the macro does not recognize &var. Any suggestions? Thank you.

SAS will not evaluate macro variable references inside of Single quote characters use double quote characters. if effect ne "&var.constant" then delete; |
