data test;
length varlist $1000;
varlist= " data x;length name $25; name='abc'; output; name='edfs'; output; run;";

set test end=eof;
if eof then call symputx('step',varlist);

I got it to work with Call execute as below, is there any other suggestions? Thank you.

Remove the & from your code. The %SUPERQ() function wants the NAME of a macro variable, not its value.
%put %superq(step);
Thanks looks like I had &step, when I was calling superq. How can I execute those?

If the goal is just to run it immediately then there is no need to put it into a macro variable.
call execute(trim(varlist));
Or instead of macro variables you can put it into an actual FILE.
filename code temp;
data _null_;
set test;
file code;
put varlist;
run;
And then use %INCLUDE to run it.
%include code / source2;
What do you want to do when you have more than one block of code to store?
For example perhaps you have a dataset that is something like this:
data test;
step+1;
length varlist $1000;
varlist= " data x;length name $25; name='abc'; output; name='edfs'; output; run;";
output;
step+1;
varlist='proc print data=x; run;';
output;
run;
Now you can put it into multiple macro variables.
data _null_;
set test;
call symputx(cats('step',step),varlist);
run;
Which you can then run independently.
&step1
proc sort data=x;
by name;
run;
&step2
Or perhaps just run them using call execute;
data _null_;
set test;
call execute(catx(' ','* STEP',step,';'));
call execute(trim(varlist));
run;
Just expand the macro variable between other steps in your program.
proc print data=sashelp.class;
run;
&step
proc print data=x;
run;
