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.
