Re: Letters to Numbers [Was - Re: [MacPerl] Hi there]

OK; how about:

$_ = "Changes Letters 2 Numbers.";

# This solution ignores everything that isn't a Letter...

# First, lowercase:
$_ =~ tr/A-Z/a-z/;

#         We can't use this:  $_ =~ tr/a-z/0-9/;
# Because we would get this:
#          0123456789 9999999999 999999
#          abcdefghij klmnopqrst uvwxyz

# So, we must be more literal:
$_ =~ tr/a-j,k-t,u-z/0-9,0-9,0-5/;

print;

__END__

What the above does:
0123456789 0123456789 012345
abcdefghij klmnopqrst uvwxyz
