Hi there,

	I'm on a XENIX 386 (2.3.2) running Perl 3.0 pl 18.  My code is doing
something very simple.  I'm reading in a text line that has a number assigned
to it (e.g. "ROW_ORIGIN 8") and I need to get the number portion out.  Once I
get the number portion out, I wish to convert this to a number.  I thought I
could do it one way, but have had to work around it...

Here's the first way I thought I could do it:

	$last_screen_line[0] =+ 0 ;		# convert to a number

But on my system, this always prints out zero.  So instead I had to do the
following:

	$last_screen_line[0] = $last_screen_line[0] + 0 ;	

Has this been reported already (or is it a feature :-) )?
