  The lookup function will tell the user what year a
  guitar is produced.

  The tables included are as follows:

      Model                    Path \ File
      D'Angelico        AXE\\DOCS\\DANGEL.DOC
      D'Aquisto         AXE\\DOCS\\DAQUISTO.DOC
      Epiphone          AXE\\DOCS\\EPIPHONE.DOC
      Fender            AXE\\DOCS\\FENDER.DOC
      Gibson            AXE\\DOCS\\GIBSON.DOC
      Gretsch           AXE\\DOCS\\GRETSCH.DOC
      Guild             AXE\\DOCS\\GUILD.DOC
      Martin            AXE\\DOCS\\MARTIN.DOC
      National          AXE\\DOCS\\NATIONAL.DOC
      Ovation           AXE\\DOCS\\OVATION.DOC
      Rickenbacker      AXE\\DOCS\\RICK.DOC

  All serial prefixes must be entered in upper case.
  Gibson is peculiar in that all pre-WWII serial
  numbers must use a serial prefix of P. All others,
  use what is valid or you will get an error message.
  Please note many of the look-up functions require
  serial # prefixes in addition to the actual number.
  Eack look-up function has an on-screen listing of
  valid prefix codes.

    If you do not like the data, simply edit the doc
  file for that manufacturer. It is the user's
  responsibility to verify and update the data,
  though the data should be reasonably accurate. Do
  not rely on any information in this software to
  guarantee the validity, or value of, a firearm.
  This is merely a data engine to process any data
  residing in the document file. The data is stored
  in ascending order so some care must be exercised.
  Each category MUST have a last year, delimited by 
  a serial number maximum value associated with it.
  For example, a field XXXXX in length would list
  the final year of production as having a serial
  number of 99999. Look at GUN \ LOOKUP \ Win94.doc
  as an example.

  A (dangerous !) feature I have made available
  is the ability for the user to interactively edit
  the actual look-up text files, rather than just
  read the data and return values. On the Lookup
  menu, the last item is an Edit Mode Toggle. When
  "û" is visible, the function simply opens the
  text for editing purposes. The edit mode can
  be toggled off by pressing <Enter> on the Edit
  mode field or simply pressing "E", the hot key
  for the toggle. Remember, the edit mode is live
  and care must be exercised during this process.
  Should a faux pas occur, simply hit <ESC> or F3
  inside the editor - either will prevent the
  file from being saved. See Edit Help for more
  details.
