just copy the following code into SAS, run it, and then open dataset s in your work library, then you would see straight away what my code does.

*========================;

%macro test1(n);

data s;

format x $10000.; x="";

format y $10000.; y="";

%do j=1 %to &n.;

x="%do i&j.=1 %"||"to 5;"||strip(x);

y="%end;"||strip(y);

%end;

call symputx("y",y);

call symputx("x",x);

run;

&x.;

&y.;

%mend;

%test1(n=100);
