Hello,
I am somewhat new to SAS and am puzzled as to how the following program behaves:
data bla;
i=999;
j=999;
do while(i ge 100);
do while(j ge 100);
put i= j=;
j = j-1;
end;
i = i-1;
end;
run;
I would expect the output to be all pairs of numbers (i,j), where i and j are in the range from 100 to 999. Instead only the j varies, while i stays at 999. What am I missing here?
Kind regards,
Hedegaard84.
Try this,
data bla;
i=999;
j=999;
do while(i ge 100);
do while(j ge 100);
put i= j=;*
output;
j = j-1;
end;
j=999;
i = i-1;
end;
run;
Youst must OUTPUT in rthe inner loop and reset the j variable after completion of the inner loop.

Yes, of course. I see why.
Thank you.
