Again, it's been a long while, but I don't believe I checked
if a Label was a filePro command.  Among things I report are:

  Label "name" is used n times (Lines: n, nn, nnn, nnnn).
  Label and Array have the same Name: "label"

  Line: nnnn - Label "nameeeee" is too long (n characters).
  Line: nnnn - Label "na" is too short (n characters).
  Line: nnnn - Label "na%me" contains illegal character(s).
  Line: nnnn - Illegal, mispelled or incomplete Label: "@wlf"
  Line: nnnn - Array Name "name" is a filePro command.
  Line: nnnn - Declared Variable "name" is a filePro command.
  Line: nnnn - Alias_Type[1] Alias Name "name" is a filePro command.

    [1] - "Alias_Type" may be an alias to a "Real Field" or "Dummy Field"
