How do I combine each row into one big row?

It looks like you are creating dynamic code.

As my experience, CALL EXECUTE is the best choice.

would you mind illustrating little bit?

For the Linlin's example .

data temp;
input tname $40. ;
cards;
sashelp.class
sashelp.cars
;
run;
data _null_;
 set temp;
 call execute(catx(' ','data',scan(tname,-1,'.'),'; set',tname,';run; proc print;run;'));
run;

ZRick,

I can't help but wonder if we're approaching this problem the right way.  There's an earlier step that generates all these lines of SAS code.  Now we're looking to reorganize them and run them.  Would it make sense to break into the earlier step instead?  Right now it generates several streams of SAS statements.  Would it make more sense for the earlier step to generate stream1.sas with all the cat=1 lines, stream2.sas with all the cat=2 lines, etc.?  You would have ready-to-run programs holding all the proper statements.

Just a thought.
