 FUNCTION HELPMOD()

  Short:
  ------
  HELPMOD() Interactively build and modify help screens

  Returns:
  --------
  Nothing

  Syntax:
  -------
  SET KEY xxx TO HELPMOD

  Description:
  ------------
  HELPMOD() creates and modifies help screens for
  HELP() which are stored in HELP.DBF.

  HELPMOD() allows online creation and modification of
  the size, location and contents of the help screen for the
  current PROC,VARIABLE combination, and stores the results in
  HELP.DBF.

  HELPMOD() is intended to be used online, during
  program execution, by the developer/programmer. It can be
  removed after development.

  By setting a key xxx to this function, the current
  PROC and VARIABLE are passed to it when the key is pressed
  during the program.

  By comparing the PROC and VARIABLE parameters against
  entries in the HELP.DBF, HELPMOD() can then provide the
  appropriate help screen for modification, or, if no matching
  record is found, allow creation of a new help screen record.

  HELP.DBF is created if not present.

  Examples:
  ---------
   EXTERNAL HELPMOD

   SET KEY -30 TO HELPMOD  && alt-F1

  Notes:
  -------
  Will not be much use during ACHOICE or MENU TO
