G'day hushbaby,
Welcome to the monastery.
You just need a single variable to capture user input.
Use length if you need to check the number of characters entered.
Use reverse to check for a palindrome.
Here's the guts of what you want:
#!/usr/bin/env perl
use strict;
use warnings;
print 'Enter string: ';
chomp(my $string = <>);
print $string eq reverse($string) ? 'Yes' : 'No', "\n";
Sample runs:
Enter string: 123
No
Enter string: 121
Yes
I'll leave you to flesh that out for your homework(?).
