Hi SAS Experts,
I just have a question on specifying series for do loops. Instead of the usual %do n=1 %to..., I would like to specify a series such that it will activate a certain set of numbers (in this case 1, 7,8,10...). But it does not work. Any ways out? 🙂
Thanks.
Best,
David
%let n_MSA=48;
%macro combineMSA(MSA);
%do n=1,7,8,10,11,17,19,23,27,28,29,35,36,38,40,44,46;
data data.diction_MSA&n.; set data.diction;
if MSA ne &n. then delete;
run;
%end;
%mend;
%combineMSA;
Do this in your macro:
%local list i n;
%let list=1 7 8 10 11 17 19 23 27 28 29 35 36 38 40 44 46;
%do i = 1 %to %sysfunc(countw(&list.));
%let n = %scan(&list.,&i.);
/* your loop body */
%end;
Do this in your macro:
%local list i n;
%let list=1 7 8 10 11 17 19 23 27 28 29 35 36 38 40 44 46;
%do i = 1 %to %sysfunc(countw(&list.));
%let n = %scan(&list.,&i.);
/* your loop body */
%end;
Please try the call execute alternate to macro do loop
data have;
do n=1,7,8,10,11,17,19,23,27,28,29,35,36,38,40,44,46;
output;
end;
run;
data _null_;
call execute("data data.diction_MSA"||strip(put(n,best.))||"; set data.diction;if MSA ne "||strip(put(n,best.))||" then delete;run;");
run;
The Macro Appendix has examples of common macro usage, including one with a macro loop.
