The following code works nicely. It uses the C rand and srand functions.
When compiling you must specify the binding directory QC2LE in order to
pick-up the C run-time library.

Spacing is probably not accurate - I cut this from a presentation not
directly from "live" code!

  D GetRandom   PR       10U   ExtProc('rand')
  D SetRandom   PR             ExtProc('srand')
  D   Seed               10U   Value
   * Get next random number
  C      Eval      NextNumber = GetRandom
   * Seed generator for new sequence (could form seed from date + time)
  C      CallP     SeedRandom( MySeed )

Hope this helps.
