http://perldoc.perl.org/perlport.html#system Failure to spawn() a subprocess is indicated by setting $? to "255 << 8" i think that is where 65280 is coming from, but i still like "fix 2", that wasnt the only place i found that fix proposed.

http://perldoc.perl.org/perlport.html#system Failure to spawn() a subprocess is indicated by setting $? to "255 << 8" I definitely missed that. Seems like an odd choice for a sentinel value, though. I'm surprised '-1' wasn't used for consistency.	[reply]
