    CVS Version 1.2, 2001/03/13 Joern Wilms
        changed the example, added a few more LONG-statements in
        comparisons. When restarting the RNG with the same seed the
        same sequence of RNGs was NOT produced due to a bug in the
        initialization subroutine --> that has been changed by now
        correctly working with base 1 arrays instead of base 0
        (randomization was thrown off course that way).
        Version 1.3, 2001/03/13 Joern Wilms
        removed debugging code that was erroneously left in
