[GEMPAK #CDH-409468]: Gempak synoptic and metar decoder input formats

Hello Steve,

You should be able to run dclsfc without any addition options.  Based on your 
use of a relative path name (os/linux64/bin/dclsfs) I'm going to guess that the 
Gemenviron file has not been sourced to your shell.  If you're using tcsh/csh, 
then you need to run 

source /home/gempak/GEMPAK6.8.0/Gemenviron

for bash the equivalent is 

. /home/gempak/GEMPAK6.8.0/Gemenviron.profile

With that done, I grab a raw synoptic report, copy it to my present working 
directory, then run dclsfc like so:

dclsfc 2013060515_syn.out < 2013060515_syn.wmo

There is a delay of about 3-4 seconds, no output to the terminal, but I now see 
the newly-written file "2013060515_syn.out" in this directory (approx. 1.8 MB).

> -s stntbl     Set the station table
> What is the format of this file? I have looked at the .stn and .tbl  files in

> stnm(6), name(32), st(2), co(2), lat(5), lon(6), elv(5), pri(2). I have also

> Is this the same format as the stntbl above? Is it needed? What are the

> -a iadstn     Set the number of additional stations
> What is the default? -m maxtim        Set the maximum number of times
> What is the default? -e PARM=value    Set the environment variable PARM to 
> value
> What is the default? -w iwndht        Cutoff height for dropsonde 
> "close-to-surface" winds
> What is the default?
