Read perldoc perlop, here is a snip: -- Bitwise And Binary "&" returns its operators ANDed together bit by bit. (See also the Integer Arithmetic entry elsewhere in this document and the Bitwise String Operators entry elsewhere in this document.) Bitwise Or and Exclusive Or Binary "|" returns its operators ORed together bit by bit. (See also the Integer Arithmetic entry elsewhere in this document and the Bitwise String Operators entry elsewhere in this document.) Binary "^" returns its operators XORed together bit by bit. (See also the Integer Arithmetic entry elsewhere in this document and the Bitwise String Operators entry elsewhere in this document.) -- Unary "~" performs bitwise negation, i.e., 1's complement. For example, "0666 & ~027" is 0640. (See also the Integer Arithmetic entry elsewhere in this document and the Bitwise String Operators entry elsewhere in this document.) Note that the width of the result is platform-dependent: ~0 is 32 bits wide on a 32-bit platform, but 64 bits wide on a 64-bit platform, so if you are expecting a certain bit width, remember use the & operator to mask off the excess bits. --- you might also want to look at perldoc -f pack perldoc -f unpack perldoc -f vec -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
