Hi Greg,

GEMPAK is a rather large set of programs for decoding, processing and 
displaying meteorological data.  One of the decoders included with GEMPAK is 
called dcmsfc, and it converts ship records into a native GEMPAK point data 
file.  These point data files can then be processed with any of the SF 
programs, such as sflist, which can dump the contents to a text file, as you 
would like.

However, if what you have are ship records in a text file, and what you want to 
produce is CSV, you would probably be better off finding (or writing) a script 
in shell or Python which re-formats the WMO text records into the structure 
that you want.
