  There is *no* such a thing as true random numbers on a computer.
  Any sequence is always pseudorandom, and the randomness properties
  depend a lot on the particular randomgenerator used (most attempt
  to simulate an uniform distribution). You best do two things:

   - use info to look up the correct syntax for these functions

   - to get started quick, search the the mail archive (www.delorie.com),
     this subject has come up so many times before...

   - read 'numerical recipies in C' which has whole section devoted on
     good random # generators
