No size is not an issue. I am writing a compare routine and the file has different sections that all need to be split up differently depending on the section to parse out the key value pairs so I can compare.
I bet that if you post a sample of this file and what you want to do with it, we can do good things.
my $last;
while (<>) {
my $current = $_; # use $current and $last here
# $last will be undef on first iteration$last = $_; }
Should work fine though, even if you're changing the values in $current and $last.
