Hi, I've been working on adding Ruby language support to our IDE "ED for
Windows" the past few weeks and am stuck understanding the marked
statement in this code:

   module Mod
     def size
       @size
     end
     def size=(val)   # what does this mean
       @size = val
     end
   end

None of the reference material I've found so far shows this. I saw it in
the documentation for: attr(symbol, writable=false) => nil

Thanks,
Neville
