I am creating macro variables inside of a do loop using the proc sql's into:, I understand that because it is inside a macro function that they are local. How do I transform to global? %global statement doesnt seem to be working.
This is the error
ERROR: Attempt to %GLOBAL a name (IDS2) which exists in a local environment. SAS 9.3
%macro num; proc sql; create table list1 as select distinct customerid from payments; quit; %do i = 1 %to 6; proc sql noprint; select customerid into: ids&i separated by ' ' from list1 where monotonic() between ((6553*&i)-6552) and (6553*&i); quit; %global ids&i;
%end; %mend num; %num;
Did you try:
%macro num; proc sql; create table list1 as select distinct customerid from payments; quit; %do i = 1 %to 6; %global ids&i; proc sql noprint; select customerid into: ids&i separated by ' ' from list1 where monotonic() between ((6553*&i)-6552) and (6553*&i); quit; %end; %mend num; %num;
Looks like you're creating a series of macro variables based on the number of observations?
It may be worthwhile to consider a data step solution instead, where you don't really need a macro at all and can use CALL SYMPUTX to create the macro variable.
data want;
set have;
length value_list $32562.;
if _n_ =1 then i=1;
value_list = catx(" ", trim(value_list), id);
if _N_ >= i*6534 then do;
call symputx ('myvar'||i, value_list, 'g');
i+1;
call missing(value_list);
end;
run;
Here's an untested sketch of how that may look.
