Getting scripts to run in LAS

[Steve Cousins <cousins@xxxxxxxxxxxxxxxxxxxxxxx>]

I am trying to get a set of scripts to run and I've been following the
example in the "Can I modify the scripts Ferret uses to generate output?"
FAQ at:

http://ferret.wrc.noaa.gov/Ferret/LAS/FAQ/scripts_and_templates.html

but it doesn't seem to be working for me.  I have been putting:

   <properties>
    <ferret>
     <script_prefix>pom_salt_</script_prefix>
    </ferret>
   </properties>

in the variables section for the salt variable and I have a script called 
pom_salt_std_gif.tmpl in the jnls directory which has the same permissions
as std_gif.tmpl.  When I go to plot the salt variable in LAS it seems to
ignore this though.  

The reason I need the script to run is that I need LAS to use the
curvilinear version of SHADE like:

	shade salt, 'X', 'Y'

If anyone has any experience doing this I'd be very interested in how it
was done.  The way I'm thinking it needs to be done is that there would be
a ?_std_gif.tmpl script for each variable.  Originally I was thinking that
there might be an environment variable or parameter being passed to the
script that would tell it which variable was being worked on but so far I
don't think that is the case.  If it was being passed then there could
just be one script that had:

	shade $1, 'X', 'Y'

or whatever.  Any idea if there is such a variable?

Thanks,

Steve
