Eduardo:
Depending on how many lines you need to work with at once and how disparate they are,
you could create a buffer of the last N lines to work on, such as:
while ( <FILE> ) {
push @buffer, $_;
shift @buffer if @buffer > 10; # @buffer will now have the current
# and last 10 lines
}
I'm not sure if this is what you want, but hopefully it helps.
Regards,
Matt
