Subject:      How do you test?
Content-Type: text/plain

How do people test SAS programs, particularly those who never use SAS
interactively?
        To test programs on only a few observations, the simplest way I
know is to use an options obs=10(or whatever) statement. This does not
work, however, when you have where statements in the program; the
program bombs at the first where statement.
        To deal with this, I often include a test macro at the top of
the program:
%macro test; if _n_ le 10; %mend test;, and then call %test
when I first set a large data set.  When testing is done, I simply
comment out the If statement. This method is a problem for certain sorts
and whenever I set a large data set many times (the problem being that I
forget to add the %test call).
        I am hoping that someone out there has developed a macro that
deals with these various issues. Otherwise, any insights from others
would be appreciated.
Thanks,
Lynn
