From the Perl Cookbook: Use pack and unpack. Here is an example (recipe 1.4): `@ascii_character_number = unpack( "C", "sample" ); print "@ascii_character_number\n"; #prints 115 97 109 112 108 101 $word = pack( "C", @ascii_character_numbers ); $word = pack( "C*", 115, 97, 109, 112, 108, 101 ); # same print "$word\n"; #prints sample` [download] -loc	[reply] [d/l]

The pack/unpack example shown above is a better methodology but you can also do it like this: `my @ascii = map { ord } split //, $string;` [download] John. --	[reply] [d/l]

Hi! `#!/usr/bin/perl -w use strict; my $String="This is Ascii"; $String=~s/(.)/ord($1)/eg; print "Ascii: $String\n";` [download] p.s. Might not be the best answer offered here, but it answers your question to the fullest ;) GreetZ!, ChOas print "profeth still\n" if /bird\|devil/;	[reply] [d/l]

Try this: `printf "%vd", "This is a test";` [download] simple enough?	[reply] [d/l]
