Hello,

Can I use an Do while inside an Marco - with loop condition. ?

%macro Week_combine();
%do loop = 1 %to &TotWeek-1;
n=0;
do while(n<=&loop);
data r2;
set Week_n;
n+1;
end;
run;
%end;
;
run;
%mend Week_combine;
I have data sets from Week_0 , week_1 ......week_n
in the above code , the &Totweek will contain the total nbr of week (week_n)
, I am trying to start from
week_1, to combine the data set week_0 and week_ 1
week_2 , to combine the data set week_0 and week_ 1 and week_2 ....etc

Error message :
098 %Week_combine;
NOTE: Line generated by the invoked macro "WEEK_COMBINE".
1 n=0;
-
180
MPRINT(WEEK_COMBINE): n=0;
ERROR 180-322: Statement is not valid or it is used out of proper orde
can someone please advice , what I am doing wrong in the code ..
Thanks
- Swamy
