     I don't know you got the answer or not.
 
     You actually don't need %str and %bquote because Macro will not
     misinterpret. Try this:
 
     %macro keepmc(yr=yr);
           tot&yr (keep=
 
           %do i=1 %to 8;
              t&i&yr
           %end;
           );
         %mend keepmc;
 
     You missed one semicolon after the ending parentheses.

     Hi,
 
     I have encountered a macro variable I can't seem to resolve and
     I don't know why.
 
     I have included the log produced by running two versions of the
     macro. I changed the tail part of var1 from %str(%( keep=) to
     %str(%( keep%=).  The two versions put out very different results:
     version 1 generated "TOT94 (keep" while version two generated
     "TOT94( KEEP%= T194 T294 T394 T494 T594 T694 T794 T894 )".  What I
     want is "TOT94( KEEP= T194 T294 T394 T494 T594 T694 T794 T894 )".
     Quotes not included in macro resolution.
 
     My final goal is to generate a data statement with several data sets
     each having a separate keep option. ie data tot1 (keep= t11 t12 t13)
     tot2 (keep= t21 t22 t23) tot3 (keep=t31 t32 t33) etc. ;
 
     Can anyone explain where my error is?
 
     Thank you,
     Kelley
