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

[Bill Jones <bill@fccj.org>]

I was thinking -

$_ = "This turns letters into numbers";

$_ =~ s/\G(\s*)(\S+\s*)/{
   foreach $chr ((split('',$2))) {
      print (ord(uc($chr)) - 64);
   } }/ge;
print;


I know this works, but maybe this is simpler ...
$_ = 'abcdef';
foreach $chr (split('',$_)) {
    print (ord(uc($chr)) - 64);
}


There are many characters that this will not work on
Like these ... but you only mentioned Letters...


(Maybe this would be better discussed on FWP list?
 I'll post follow-ups there :)
