LV-DLL.DLL is a dynamic link library function, that can be used
by LabView.
It hooks an interrupt, on the first call to ISR_FUNC, and on
subsequent calls, returns a count of number of times interrupt
has occurred since last call to ISR_FUNC.
Note that I have put a "beep" routine in the DLL, to give audible
confirmation -- it toggles on and off with alternate interrupts --
in the case of the keyboard interrupt-9, an interrupt is
generated every key press and release, so the beep stays on for
as long as a key is held down.
Example of usage is LV_DLL.VI, which hooks interrupt-9.

Source code is supplied, and you will need MASM version 6.1.
PROCEDURE:
MASM 6.1 fully installed.
Go into Windows.
Go into a DOS box.
Go into directory containing these files.
Type "PWB" (runs Programmer's Workbench).
Open the Project: /project/Open-Project/LV-DLL.MAK
   --- open as a non-PWB make file.
Choose /Project/Rebuild-All.
PWB will generate LV-DLL.DLL.

USING in LABVIEW:
As per example, LV-DLL.VI, *BUT* you will have to reconfigure
the DLL function ---
right mouse button over the DLL, and change the path to where
the LV-DLL.DLL is located.
