SP_HELP

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
