If you want your program to pause during execution if, for example, you
have a lot of output you could insert statements like this:
{ my $trash = <STDIN>; }
What this does is waits for you to hit enter and takes whatever you
typed (if anything) and puts it into the variable $trash, which then
goes out of scope because the block it's in ends.
Sometimes when I want to quit out of a loop, I'll do:
{ my $trash = <STDIN>;
last if $trash =~ /q/;
exit if $trash =~ /x/; }
But the more simple example will probably work for what you want.
Hope that helps,
