FUNCTION 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
