I have just finished implementing the complete netCDF library from
within IDL on VAX/VMS systems. I used the call_external routine to call
the C netCDF library which I linked as a shareable image. This could be
done quite simply for many Unix systems (SunOS, AIX, HP, etc.), although
one additional layer of C interface routines is needed under Unix.

I wrote IDL "wrapper" procedures with the same names as the netCDF C
routines, so the calling interface is almost identical to that
documented in the NetCDF User's Guide. The IDL routines do a lot of
bookeeping, type conversions, etc. which considerably ease the
programmers task compared to writing in C.

Anyone interested in getting what I have done let me know. I am
aware that netCDF is going to be added to IDL directly soon, but I wanted
to get started now. My routines should also work fine from PV-WAVE
wheras PV-WAVE may never have direct support for netCDF.
