in reply to pack, unpack and internal represenation of numbers

pack and unpack convert things to and from an internal string representation. In your example, unpack interprets the scalar 0x01020304 in a string context, which is "16909060".

On the other hand, pack("L", 0x01020304) returns a string which is along the lines of "\x01\x02\x03\x04".

    Yes!

    Explaining it fully for those that don't understand yet: 

    From the string "16909060", 
'1'=ASCII(49)  '6'=ASCII(54)  '9'=ASCII(57)  '0'=ASCII(48)  etc.
