RE: Random Number generator

["Leland, David" <dleland@xxxxxxxxxx>]

Try this ILE RPG code.  It uses the CEERAN0 API.  If you want a 5 digit
random number simply call this program passing in a valuie of 10000 for
MINNBR and 99999 for MAXNBR and it will pass back to you the RNDNBR. 
Works for us.  Check out the documentation on the CEERAN0 API for info
on it's "seed" parameter.  We simply initialize it to 0.  You may want
to do it differently.  As always, comes w/ no guarantee and user is
responsible for thorough testing before using.
