r/w binary

[Joel Christensen]

I'm thinking more about handling binary files. With the C version I 
would write a int for how many letters in the string, then put in the 
the string along side ([0005][house]). That way I can have any character 
at all (though I just thinking of char's).

Actually, I've just looked the output file and it's a text file. So in 
that case I would use read line to have spaces in strings, though what 
if I wanted to have new line character(s) in the one string. I still 
want to work with binary files.
