I just recently discovered some functions that are good for this sort of thing. seek() and tell(). tell(FILE) will return your current position in the file FILE, and seek(FILE, $n, 0) will send you to the location in FILE stored in $n. Use them like this: 
# open your file
$top_of_file = tell(FILE);
# go fetch your variable
seek(FILE, $top_of_file, 0);
# now you're back at the top

They're handy in other situations, too. You can tell() any number of positions in the file, and go back to them at will. I bet there's a JAPH in that concept somewhere...
