seek( FH, 0, 0 );
...the first argument refers to the filehandle, the second argument to the offset, and the third one of three positions in the file(beginning, current, end).
I see my mistake was thinking of 'offset' as equivalent to line numbers, which it is not. It refers to byte positions. So, my new question is: Is 'byte positions' really as simple as it sounds(the positions of the byte in the file)? So if I knew the exact byte position that I wanted to seek to I could enter it as the offset argument and be taken right there?

You are correct in your interpretation. And it is as simple as that. It only gets complicated if you need to do something like: "go to the line exactly half-way through the 20M file," since it's nigh on impossible to know the byte position of an arbitrary line number without reading through the entire file, a byte (or block, as it were) at a time. =( But as long as you know the byte position already, you're good to go.

One more:
Does 'byte position' apply only to the position of the beginning of the line, or the position of any single byte within the file?

That did it. I guess I misinterpreted how to use 'seek'...time to hit the books again...THANKS!!!
