Hi John. When it says Usage: POSIX::getchar() it's trying to tell you that 'getchar' takes no parameters. In any case it's the same as the built-in getc function, so try it like this: perl -e '$ab = getc; print "$ab\n";' HTH, Rob -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
