发帖数: 132 | 1 How to assign a bunch of numbers in a %do loop in a macro?
%do i=1, 3, 6, 7;
....
%end;
It doesn't work in SAS
Any sugggestion? | A*******s
发帖数: 3942 | 2 not sure if there is a better way but i do it in such a stupid way:
%let charstr=1 3 6 7;
%let i=1;
%do %while (%scan(&charstr, &i) ne );
%let j=(%scan(&charstr, &i);
%let i=%eval(&i+1);
......
%end;

data index;
input i;
datalines;
1
3
6
7
run;
Then
%do j=1 &to 4;
data a;
set index (obs=&j);
call symput('i',i);
run;
/*do whatever you want to do with &i here*/
...
%end;
This is what I usually do this kind of work. Remember macro in SAS is not as
easy as function in C. SAS is dataset oriented in most of the cases.
