Hello everyone,

Why if I use (5 or 6 )to replace (3 and 4) will NOT get 'a' in the SAS log?

Thanks!

Mike

/*1.*/%let g=2;
/*2.*/%let cc3=a;
/*3.*/%let k= %eval(&g+1);
/*4. */%put &&cc&k;


/*5.*/%put &&cc%eval(&g+1);
/*6.*/%put &cc%eval(&g+1);

cause '&' resolves before %eval computation.

&&cc%eval(&g+1) -> &cc%eval(2+1) -> 'warning: cc not resolved' ->&cc3

The %eval is just going to concatenated to the resolution of the macro variable &&cc or &cc.  Compound macro variable resolution is not available in that syntax.

%let g=2;

%let cc3=a;

%put %unquote(%nrstr(&cc)%eval(&g + 1));

Hi Mike,

You might also use the following alternative:


     %put %superq(cc%eval(&g+1));
