I've been using IDL for about 7 years and have pretty much abandoned other languages. I enjoy it when people come to me and say "but IDL can't do that" and I show them how to do it. I've always had excellent response from the IDL people, no problem getting help. I don't know much about PV-WAVE except that it is based on IDL and as a language is very much the same. As far as point and click, I've been writing such programs in IDL for awhile using the wmenu function. This probably isn't the feature that PV-WAVE means, but it works just fine. This feature will be much improved in future releases of IDL I'm told. What amazes me most about IDL (and PV-Wave) is that anyone would still use FORTRAN or similar languages.
