  Much better! Now parsing most fields reasonably well.

  Revision 1.2  2002/10/31 19:25:22  simon


  This package of work is to take a parser which correctly recognised
  all the record and field boundaries, and try to make it read actual
  data. The DDR is now reading correctly (I believe) but the data are
  not being read, primarily because (I think) I'm not correctly making
  use of the data I read from the DDR.

  Revision 1.1.1.1  2002/10/29 11:27:33  simon
  More or less parses
