Bingo, James! Sorry for my ignorance, but I am just beginning with Perl.

Easy enough.
The script is:
#!/usr/bin/perl use warnings; use strict;
Above, you are asking Perl to make you play by the Good Programmer rules. One of those rules is, you must declare a variable before using it.
$greeting = "World";
Here you use an undeclared variable. Usually, you'll declare a variable with "my", so change to above line to:
my $greeting = 'World';
Hope that helps.

print "It matches\n" if "Hello World" =~ /$greeting/;
