It probably depends on how many of those not-yet-implemented routines you think you have to use in the course of a normal day. Cheers, David -- David Fanning, Ph.D. Coyote's Guide to IDL Programming (www.dfanning.com) Sepore ma de ni thui. ("Perhaps thou speakest truth.")
I use it only occasionally, when I want to give to someone a program I wrote in IDL. But I frequently find that I used some library routine not in GDL, so it does not help. I think GDL is a very good idea in principle, but it seems to me that the project is not very active, so the missing features will remain missing for a long time. It seems to have the significant advantage, compared to IDL, of talking to Python without the added cost of Slither, but I have never tried to use it with Python. In a related issue, does anybody use PV-WAVE? If so, how does its current version compare to a current IDL? I did not find any PV-WAVE topics in recent years in this group.

The language features are fully implemented, but the library is obviously not complete. Also, you must compile GDL before using it, which is not trivial since it has several prerequisites.

It has existed as an rpm in the Fedora repository, since around Fedora 5 or 6. Which makes it a lot easier to install (and to work after installed) than IDL, which frequently breaks when a new version of Fedora comes out. The package I have installed is gdl-0.9-0.5.rc2.20090312.fc11.x86_64

If one needs to deal with FORTRAN unformatted binary files (as I do), this is not an option since, as I learned recently, this feature is not implemented (/f77 or /f77_unformatted will lead to "keyword not allowed" message). However, with GDL this works nice. Cheers, Florian
