You do have NCAR Graphics and netcdf installed, right?

First, are you on the system you want to run NCL on? As in, sitting at
the console? I'm assuming the answer is "yes" as you were playing with
Xeyes.

If that's the case, from a command line, execute the program without a
script file to execute, and you'll be in interactive mode. Then, you
can cut'n'paste lines in, and watch for errors.

instrumenting with prints is similar to the good old days (Fortran, for
me). See the function at

I'd say, Welcone, but I'm at texas a&m... and I'm an old programmer
(maybe older than Dennis:-).
