Dear Zafer,

I fully agree with the opinion of Johannes Mulder. With both HP VEE and LabView
you are able to create test programs which can do the same operations, however I
recently found one difference which can be very essential in some applications.
The difference was about multitasking capabilities with Windows 3.1x.

The testbench I used was an application program which collected the data of a
probe station via a GPIB link (NI). The concurrent process was simply a counter
in HP VEE. The counter process puts the system performance drastically low, so
that that the concurrent application cannot collect the data fast enough to
update the screen and even worse, don't know anymore the positions of the probe
station, which finally generates a timeout.

The same testbench was tried with LabView 4.0, because I heard from someone that
LabView has multitasking capabilities. A counter for example should not lock up
the computer or prevent other applications from executing. This approach worked
correctly.

I think HP VEE doesn't have these capabilities because in the early days it was
developed for UNIX platforms which were really mulitasking. When HP VEE was
ported to PC they apparently forgot the restrictions of Windows.

With kind regards,

Arjen Bakker.
