That proved very useful. Thanks.

I meant that the hex string I was gunning for was, say 110 bytes into 
the file, and I wanted everything between 110 and 200 to be read in in 
hex. I meant I'd do something like
f = File.open("name","r")
for i in 0..109 do
f.getc
end

to bump the pointer forward 110 bytes.
