Hi Ben,

I looked a little while ago and couldn't find any pre-existing IDL
code to encode URL strings. But it's a pretty straightforward
search-and-replace operation that shouldn't take too long to code up.
In case you need it, there's a list of the required codes on
Wikipedia: http://en.wikipedia.org/wiki/Percent-encoding

Incidentally, there are some scripts that access web pages directly
from within IDL, such as webquery from the Goddard library. These
may be slightly faster for repeated use, since they don't involve
spawning external processes. I believe there's also a web access
object in IDL 6.4 now, but I'm stuck back at 6.2 right now.
