Hi Fellow IDLers,

I've been working concurrently with IDL, MS C, and the National
Instruments VISA library for awhile now. It never occurred to me until
now to ask if anyone has interfaced IDL with NI-VISA. The task actually
boils down to the topic that I've been avoiding learning due to my
current workload - having IDL utilize an external predefined DLL. I'm
suspecting that there needs to be an intermediate layer between the two
- something of the 'DLM' form. If anyone can advise, please do.

Also, is there a purchasable reference that does a good job of
explaining the above process?. David or Ronn, if you cover this one,
I'll break down and spring for a copy of your book :) .

On an unrelated topic, there has been mention of the MOMENT routine
recently. I've just done some digging through it in another
speed-related issue. If you need to perform alot StdDev's or Means, you
might consider writing your own, as I did. MOMENT is calculating *all*
the calculations (Skewness, Kurtosis, et al) *all* the time - no matter
what you ask for. In fact, calling the STDDEV routine, only routes the
process over to MOMENT - whee!


Thanks all,

-Bill B.
