Hi monks,

Long time no see! I have a little trouble when I show off perl to my colleague! :(
Below is my script used to translate hexadecimal to ascii. 
open ($fh,"<vip.txt");
my $text = <$fh>;
chomp $text;
map {printf ("%c", $_)} split (',', $text);

__vip.txt__

I suppose 'split' let perl treat element as string type. But how can I reverse it to number? Any answers are appreciated!

I am trying to improve my English skills, if you see a mistake please feel free to reply or /msg me a correction
