ick, this doesn't sound good. However, I'm not really worried about the
GUI part, the code I have looks like it has just one program that takes
care of all the interface stuff, and I think I can rewrite this because
I've used Motif before. What I'm really worried about are all the
number
crunching routines that I have that are written as procedures - they do
lots of spatial processing and such, and they look like they are just
number crunchers without any specific graphics calls. I would prefer
not to rewrite these if I can get away with it. Are there any things
that I should be on the lookout for between IDL and PVwave in these that
would make the thing hang up if I tried to just rewrite the GUI and
stuff the *.pro number crunching code behind it?
