Mark,

FWIW, I don't often comment on programming examples posted here even
though I usually try them out. I was floored by the benchmark
comparisons that I got when checking out your idea. I have a Win95
Pentium 200 32Mb machine w/ IDL 5.2.1. I didn't run an exact time count
but I estimate your idea being ~30 times faster (~4 seconds vs. over a
minute). Also, and perhaps more importantly, IDL consumed only 25-26
Mbytes operating on your code and 125-126 Mbytes on the original
(obviously churning like crazy)!!!

I regularly work with large arrays and need to go back into my
application to see if I can utilize this.

Thanks for an eye-opener!

Bill B.
