        I found this C routine in a magazine.  I wanted to use it because I 
an algorithm that had a pedigree: this particular routine was based on an 
that would generate a "scientifically" random data stream.  The C function 
didn't provide the needed accuracy that the researchers needed.

Why an algorithm with a pedigree?  We were using it to randomly select truck
drivers for drug testing, and the legal folks wanted to be able to demonstrate
that the means was truly as random as possible.  This particular routine will
generate 2^31-1 numbers before the pattern begins to repeat itself.  That's 

I needed to translate it to RPG because we didn't have a C compiler.

Hope that helps!
