Great tip!!!! I had a alphanumeric display to show the value. But the
display didn't show the value as an array. You're right, the value is in an
array 1D format. How do I convert this to a scalar format?
Thanks,
Ron

Works fine here.
Sounds like you're sending it an array. Hold down Shift and then click the
mouse on the wire going into the Meter object. You will get a box that
will tell you if you're sending it a scalar or an array.

I created a simple program to test this and it works fine. Are you
synchronized between the two inputs? Obviously if one input keeps advancing
while the other does not one trace will advance and the other will disappear
momentarily.
A small example program might be in order.

VEE 3.2 has been shipping for a year and is supported on Win95. We do not
guarantee proper operation of VEE 3.12 on Win95.

Hi folks,
I have seen similar problems with the strip chart object "losing" data
and then "finding" it again. In my case, the strip chart object is
displaying two traces, updating the traces every half-second or so,
and then autoscaling. About every five seconds, one of the traces will
disappear (always the same trace, the second one), and then reappear
about 2 seconds later (with all of its previously-recorded data
intact). I'm using VEE 3.21 on NT3.51.
Anybody else seen this problem?
Regards,
Nate Gardner

VEE 3.12 doesn't work very well under Win95. It's only supported on Win3.

I am not sure I understand the question. A Meter swallows Reals OK and they
should be scalars in any case. Please clarify.
