Hello SAS83,

What do you mean "Using ONLY with SAS Macro Statements"?

The easiest and straitforward way to do it is this:
[pre]proc SQL;
select num into :y separated "," from x
;quit;
%put y=&y;
[/pre]
"Using ONLY with SAS Macro Statements" approach results in
[pre]%macro a;
proc SQL noprint;
select COUNT(*) into :n from x
;quit;
proc transpose data=x out=t prefix=c;
run;
%do i=1 %to &n;
proc SQL noprint;
select c&i into :c&i from t
;quit;
%end;
%let y=%TRIM(&c1),%TRIM(&c2),%TRIM(&c3),%TRIM(&c4);
%put y=&y;
%mend;
%a[/pre]
Is this what you need?
Sincerely,
SPR
