in reply to passing hex argument as string

Well, I'm not sure I'm getting what you're getting at. First of all, the call_f2 sub is entirely superfluous. Now you're comment says that you're trying to print 100. I'm not sure what that means. If you want to print $num in base-10, you should be able to just print it out. If you want to print it in hex (base-16), try:

printf "%x", $chr;

Are you sure it was a book? Are you sure it wasn't.....nothing?

yes I am familiar with printf function. But I can not do that. Beccause the function that takes $chr is FIXED, and I can not change it. So what I want is a function that: # takes a hex number 0xff # returns string "ff" and NOT 255	[reply]

That's what `sprintf("%x", $hexnum)` [download] does. If $hexnum is 0xdeadbeef, the sprintf will return "deadbeef". (Use %X instead of %x if you want "DEADBEEF".) (updated to correctly say sprintf instead of printf)	[reply] [d/l]
