# ALWAYS use strict and warnings (see: strict, warnings)
use strict;
use warnings;

# In general, keep comments on separate lines from your code
# the first line in the world of perl.
print "My first Perl script\n\n";

# Declare the variables, and make them descriptive
my ($multiplier, $max_number);

# Get some input from the user
# Lets also validate it (we are only interested in "numbers")
# See perlre & perlretut

    last if $max_number =~ /^\d+$/;
}

# Now, print out the table
# Use a "perlish" loop rather than a C-style one
# By doing it this way, we don't need the loop variable
# And we can instead just operate on $_
print "\nThe table is:\n\n";
