in reply to Re: On Scalar Context
in thread On Scalar Context

The perlfunc pod does define the return value of the 4-arg-select:

Most systems do not bother to return anything use- ful in $timeleft, so calling select() in scalar context just returns $nfound.

This is from the perlfunc manpage of perl 5.8.1.
