None if you were thinking ahead and put all your binary
data in XDR format. :-)
If you didn't, ByteSwap will solve most of your problems.

Get IDL 5.0 so you don't have to worry at all about file names.
Make them as long as you like. (Although other software that you
will probably have on your machine will still not *totally* like
long filenames. Don't you wish you could pay a fortune and update
all your software at once? :-)

My experience with IDL NT has been terrific. I love it. There are
certainly bugs here and there, but these will all be gone in the
next release. ;-)

Even a 266 MHz PII is just a doorstop without software. Seems to
me that a large part of the value of any system is the software
you put on it. The question is, do you save $1500 of time and
effort using IDL as opposed to doing whatever it is you do some
other way. Maybe you could write C programs. How much time and
effort do you think it would take you to learn to write your
programs in Visual C++? In my situation, I would probably starve
before I figured it out. Makes IDL look like a bargain, at least
to me.
Cheers,
David
