How to add two hex numbers?

[CFtaxtron]

I need to add two hex numbers together and having a problem I can't figure it out

$digest = md5_hex("qawsedr"
$digest1=$digest+33C93DC8827080D429A127089CEC3745;
$digest2 = md5_hex($digest1);

I get the error message

Bareword found where operator expected at C:\Inetpub\

http://wwwroot\TestBed\bb.pl

line 7, near "33C93DC8827080D429A127089CEC3745"
(Missing operator before C93DC8827080D429A127089CEC3745?)

Is there anything special I have to do to add two hex numbers together.

Thanks

Tim

Do you really need to ADD them together, or could you just OR them? If you really need to add them (arithmetically) you'll have to pack them into a real number, then add them, then unpack them again. Otherwise perl treats hex numbers as strings.
