KBDESC()

  Short:
  ------
  KBDESC() Keyboards character 27 (escape) when key pressed

  Returns:
  --------
  Nothing

  Syntax:
  -------
  SET KEY xxx TO KBDESC

  Description:
  ------------
  Allows setting an alternate key to the ESCAPE key.
  ESCAPE normally means 'get me outta here', but sometimes is the
  key you need to indicate the user is done selecting or some
  such. This function allows setting another key (e.g. F10) to act
  as the ESCAPE key.

  Examples:
  ---------
   SET KEY -9 TO KBDESC

  Warnings:
  ----------
  Be sure to issue a   SET KEY xxx TO   command to
  un-map this function when done

  Notes:
  -------
  Declare as EXTERNAL i.e.

  EXTERNAL KBDESC

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

HELP()

  Short:
  ------
  HELP() Provides context sensitive popup help

  Returns:
  --------
  Nothing

  Syntax:
  -------
  SET KEY xxx TO HELP

  Description:
  ------------
  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, HELP() can then provide the appropriate
  help screen for the user. If no matching record is found, HELP()
  displays a 'No Help Found' message to the user.

  HELP() works in conjunction with HELPMOD() which is
  used to create help screen records for the HELP.DBF. HELPMOD()
  allows online creation and modification of the size, location
  and contents of the help screen for the current PROC,VARIABLE
  combination.

  Examples:
  ---------
   EXTERNAL HELP

   SET KEY 28 to HELP

  Warnings:
  ----------
  The SET KEY that called this proc is still active
  inside the proc. You may wish to modify the proc to turn off/on
  the set key.

  i.e. if called with key 28 (F1)

  at start :  SET KEY 28 to
  at end:     SET KEY 28 to HELP

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