What am I doing wrong? Here are 3 attempts at trying to use getchar. It seems I am following the Usage, but I guess not.
$ perl -e 'use POSIX;$ab="10";$pab=POSIX::getchar($ab);print $ab,"\n",$pab;' Usage: POSIX::getchar() at -e line 1 $ perl -e 'use POSIX;$ab="10";$pab=POSIX::getchar(STDIN);print $ab,"\n",$pab;' Usage: POSIX::getchar() at -e line 1 == I entered the "abc" in this example === $ perl -e 'use POSIX;$ab="10";$pab=POSIX::getchar(<STDIN>);print $ab,"\n",$pab; ' abc Usage: POSIX::getchar() at -e line 1 Thanks, John -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
