Buffered Files & Associative Arrays

[Unknown W. Brackets]

Well, this still happens for "File", so it's not as if it's a 
BufferedFile issue.

As it happens, the problem is the way you are abusing File's buffer. 
You're taking the line, and using it... where the stream is overwriting 
that space with new data.

Find:

Ar[line] = n;

Replace:

Ar[line.dup] = n;

That should solve your problems.
