  2.         Display program for BL files, which record broadcast server activity.
  3.         This code is not particularly portable. It was written for Microsoft C under DOS.
  4.         It will also compile under Quick C for windows, and the unixtime module sorts
  5.         out the problem that ANSI standard time is not the same as good old unix time.

  7.         fFixed -     This flag is FALSE for early UoSAT-3 and UoSAT-5 BL files because there was
  8.                           a bug in the onboard logging task wich caused incorrect counts in the
  9.                           entries for overwritten requests and un-fresh requests.
