Yes, but neither of those seem to be sufficient. In my case (and I
believe in the case of the original poster), we've got VAX floating
point numbers to be read into IEEE format on a machine who's local
format *is* IEEE. Unless I'm missing something in my reading of the
manual, that's not covered by IDL's conversion functions.
I've got some code lying around somewhere that I wrote to go from
VAX to IEEE floating point (single-precision), which I'll dig up if
I don't see any other solution go by before I get back from my travels.
