Subject:      Re: How do you test?

A method I use to test is to take a random sample of the records using
the uniform function.  Sometimes observations at the beginning of a
dataset will not provide a sufficient test of the code, especially if one
is doing first and last.by variable processing.
 
Consider the following pseudo-SAS code which will use a 5% random sample
of the input data to test the code.
 
Data test;
        Set xxxx;   (or infile)
 If uniform(0) < .05;
...
 Rest of sas code to test.

Run;
