Whats the problem about this loop?

liudw925 — Thu, 14 Jun 2012 09:59:12 GMT

data _null_;

n=3;

do i=1 to 5;

if i<n then

do;

continue;

end;

else

do;

leave;

end;

put i=;

run;

The sas log:

9 quit;

10 data _null_;

11 n=3;

12 do i=1 to 5;

13 if i<n then

14 do;

15 continue;

I am not seeing any errors when the above code was submitted.

If I replace 'else' with 'els' and submit I get the WARNING but not the ERROR.

What version of SAS and environment are you using?

Thank you for your help.

My SAS is version 9.2, and i used enhanced editor and submitted. But i always got ERROR , there were some question marks in the log. Very strange! I don't know why. I tried to install SAS again and the problem was still not resolved.

By the way, all other programs run correctly on the SAS.

I have solved this problem.

It is the SAS problem, perhaps a bug in my download SAS 9.2.

I installed SAS9.3, and then everything is OK.

Thank you anyway.
