\_ I'm looking for a program that will take either a decimal, hex or octal \_ input and give me its decimal, hex or octal output. Can anyone tell me what \_ I'm looking for? \_ perl? Bah. Use that on big numbers. For small numbers, RTFM. In particular, 'man ascii' and pick the conversion you want. You'll also get the popular %c conversion as well, all in a nice tabular format. :-) David OB perl variant: --snip-- #!/usr/bin/perl my $arg = shift; eval "\$i = $arg;"; printf "%s is one of: 0%o or %dd or 0x%X\n", $arg, map {$i} 0 .. 2; # who said map wasn't useful?
