Really?
I don't think you've tried hard enough. :)
#!/usr/bin/perl
open TEST, ">test.txt";
print TEST "this is a test\n";
open TEST, "test.txt";
my $l = <TEST>;
print "TEST before edit: $l";
open TEST, "+<test.txt";
seek TEST, 5, 0;
print TEST "was";
open TEST, "test.txt";
$l = <TEST>;
print "TEST after edit: $l";
