Ahhh ... now that explains all those FL-3 errors that I always saw but never 
tried to deal with since everything typically worked ... didn't know about the 
^ trick, I'll have to try that!

Jason,

The problem is a bit more subtle. GEMPAK converts file paths to all lowercase 
before creating a new file. So, your GDFILE entry 
"/VRS/expTrackFax/topography4.gem" is converted to 
"/vrs/exptrackfax/topography4.gem", which is not the correct directory. When 
opening an existing file, the original case of the file is checked first before 
changing to all lowercase. This is all legacy from the VAX/VMS days. In order 
to override this default behavior, preface the mixed case file path with a "^". 
This will preserve the mixed case and skip the conversion step.

Scott

To whom it may concern,

I am trying to create a .gem file using gdtopo and I get the following error:

[FL -3] Cannot create file topography4.gem

Do you know what is going on and how to resolve this issue?

Attached is my script.  Thank you for your time.

The first thing I would look at is to see it you have write permission to the
directory: /VRS/expTrackFax

If you do, see if you can create or modify (if it already exists)
the file /VRS/expTrackFax/topography4.gem exist.  Try to execute:
touch  /VRS/expTrackFax/topography4.gem
and see if the file exists and the time stamp on it is current:
ls -l /VRS/expTrackFax/topography4.gem
