[aprssig] Programming Language Advice

I'm sure one really ugly line of perl will do it, though you may never 
be able to figure out HOW when you go back and look at it again later.

Python seems to be a lot less ugly, but I'm not familiar enough with it 
to know how to set this one up.

I'd probably just do it in C, but that's because I wouldn't have to 
think about how to do it, not because it's the best language (or even a 
very good one) to do it in.

Come to think of it, I could do that in PL/SQL (the decode function 
would handle the compass directions) but that doesn't do you much good 
unless you're working with Oracle.
