COMPARE/2SAM table col1 col2 
	kolmogorov two-sample test
\us\pu
Purpose:      
             Performs a Kolmogorov-Smirnov Two-sample Test on two columns
             of a table
\up\sy
Syntax:       
             COMPARE/2SAM table col1 col2 
\ys\pa
             table = name of the table
\ap\pa
             col1  = first column
\ap\pa
             col2 = second column
\ap\no
Note:        
             The command will return the Kolmogorv-Smirnov D statistic as
             well as the probability of exceeding D under Null Hypothesis,
             the Null Hypothesis being : 
             "The two data sets are drawn from the same distribution function"
             Warning : The probability becomes accurate when the size 
             of the sample is large enough (>=20)
