Re: Extracting a bit of a scalar variable

Hello Praveena, I recommend you to use pack and unpack function. I believe you can use this to convert the digit to binary and also extract the digit of your choice from the result. perldoc -f pack type this command at your linux console if any to get the help on pack. Regards Nishanth --- Prav

Extracting a bit of a scalar variable

Hi All, I am newbie to PERL.I think this is a very simple question to ask. Is there any way to print a particular bit of a digit after converting to binary form. Thanks in Advance, Praveena -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

arguments

Maybe I'm getting old, but I'm starting to thing that if there is a method/sub/function/whatever that has more than one argument, one should always pass the args as a hash reference. This eliminates the problems of getting the variables out of order. It's probably slower and higher memory usa
