 FUNCTION FORMLETR()

  Short:
  ------
  FORMLETR() Interactive formletter and mailmerge utility

  Returns:
  --------
  Nothing

  Syntax:
  -------
  FORMLETTER([aNames,aDesc,aTypes];
        [aMoreFuncs,aMoreDesc,aMoreHot])

  Description:
  ------------
  Provides a menu driven interface to the creation,
  modification and merging/printing of form letters with DBFs.

  Three field arrays may be passed - [aNames] is an
  array of allowable field names, [aDesc] is an array of
  field descriptions, and [aTypes] is an array of field types. All
  fields are used as a default, with field names being the default
  field descriptions. Pass all or none of the first three arrays.

  Three additional arrays may be passed for up to 30
  additional hotkeys.

  [aMoreFuncs] is an array of functions which will be
  placed between .. delimiters. [aMoreDesc] is a corresponding
  descriptive array of these functions, to be shown when the user
  presses F1. Format:

       "hotkey     description "
        | column 1 |column 17

  [aMoreHot] is the corresponding hotkeys as their
  numeric ascii values.

  All three arrays must be passed, if any, and all must
  be of same length with no null or undefined elements.

  You could use these for Printer control, special
  combined fields, etc. Be sure the functions you wish to call are
  available to the linker, usually by declaring them EXTERNAL.

  Examples:
  ---------

  USE CUSTOMER

  aFields := {"Fname","lname","mi"}
  aDesc   := {"First","Last","Middle"}
  aTypes  := {"C","C","C"}

  * hotkey arrays
  aMoreFuncs := {"BOLD_ON()","BOLD_OFF"}

  aMoreDesc  := {"F5    BOLD PRINT ON", "F6    BOLD PRINT OFF"}
  aMoreKeys  := {K_F5,K_F6}

  FORMLETR(aFields,aDesc,aTypes,  ;
             aMoreFuncs,aMoreDesc,aMoreKeys)

  //or...

  USE CUSTOMER
