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
