about quit statement

[deleted_user]

I just wondering about 'quit' statement.

My SAS program is follow as, and generation program was based on "proc iml"

%macro simulation (ncopies);
%do j= 1 %to (0 +&ncopies);
%generate (&j)
%end;
%mend simulation;

/* Dataset for 20 copies*/
%simulation (20)
run;
quit;

Is the quit statement required in this case?

In my procedure, first runnig was ok. but when I'd re-runed repeatedly, that time, I've gotten some problem message.

Perhaps you are running into this issue:

It seems that PROC IML terminates with a QUIT; statement.
