I'm not familiar with how EditPlus relates to taking input in a Perl script.

The following script will prompt for and take user input via STDIN, place it in a variable named $input, strip away the trailing newline, and will print what the user typed in, to STDOUT.

#!/usr/bin/perl

use strict;
use warnings;

print "Enter your input:\n";
my $input = <STDIN>;
chomp $input;
print "You typed: $input\n";
