3 diffrent way of writing the same thing, a lot of time PERL have more than one way of doing things. I have learn to write <STDIN> upper letters to show it is a stream You have 3 standard streams (without open anything) a. STDIN (Defaults reads from keybord b. STDOUT (Default write to the screen) c. STDERR (Defaults write to the screen to) STDOUT and STDERR have a mening that you allways write errormessage to STDERR and can redirect it to eg. a errorfile. IF you haven't redirect STDIN it reads from KEYBORD to MEMORY and don't give you any file that you can use, if you like to save data open a file and write alla data to it // Anders -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
