Hello,   i have a macro code in the following structure:   %let Waehrung = 1; %macro Pruefung (sparte=, Marktsegment=, WAE = &Waehrung); Data temp.&sparte._&Marktsegment.;          set temp.&sparte._&Marktsegment.; run; %mend Pruefung;   It works.   But if i add the "if then do; end" like:   %macro Pruefung (sparte=, Marktsegment=, WAE = &Waehrung); If WAE = 1 then do:   Data temp.&sparte._&Marktsegment._1;            set temp.&sparte._&Marktsegment.;   run; end;   If WAE = 2 then do:   Data temp.&sparte._&Marktsegment._2;            set temp.&sparte._&Marktsegment.;   run; end; %mend Pruefung;   If doesn't work any more. ERROR 180-322: Statement is not valid or it is used out of proper order.   Has someone an idea, why?   ... View more
