Speaking of online help...
You may recall that long ago Andrew Cool and I fussed with an online
help system for IDL 5.5 that used IDLWAVE resources to get around the
PDF help system that was then provided with IDL.
Imagine my surprise this week when I accidentally type ...
IDL> xdl
What the heck?!?
Digging a little deeper I have found that...
IDL> xdl, /no_block
while not pretty, is pretty handy. That said, I think the new online
help system, regardless of what I might think of the contents, is very good.
Cheers,
Ben
