Installs a WIL extender dll.
AddExtender(filename [,version [,alternatefilename]])
(s) filename: WIL extender Dll filename
(s) extender version: [optional] minimum required extender version number.
(s) alternate filename: [optional] 64-bit WIL extender Dll filename. Note that 64-bit WinBatch still treats the first parameter as the file name of a 64-bit extender when no third parameter is present.
(i) @TRUE if function succeeded
WIL extender Dlls are special Dlls designed to extend the built-in function set of the WIL processor. These Dlls typically add functions not provided in the basic WIL set, such as network commands for particular networks (Novell, Windows for WorkGroups, LAN Manager and others), MAPI, TAPI, and other important Application Program Interface functions as may be defined by the various players in the computer industry from time to time. These Dlls may also include custom built function libraries either by the original authors, or by independent third party developers. (An Extender SDK is available). Custom extender Dlls may add nearly any sort of function to the WIL language, from the mundane network, math or database extensions, to items that can control fancy peripherals, including laboratory or manufacturing equipment.
Use this function to install extender Dlls as required. Up to 32 extender Dlls may be added. The total number of added items may not exceed 750 functions and constants. The AddExtender function must be executed before attempting to use any functions in the extender library.
The AddExtender function only needs to be executed once for each extender dll, in each WIL script that requires it. If you attempt to load the same extender dll twice, using the AddExtender function, the operation will be ignored.
The documentation for the functions added are supplied either in a separate help file that accompanies the extender Dll.
