Hi All,

Here is my confusion. The above sets
:$in = '-', :$out = '-', :$err = '-',
to "-" as the default.
But if you leave
:$out and :$err
off the run line, STDOUT and STDERR do not
get captured and are sent to the console.
...that's exactly what "-" means.
G'luck,

If :out and "err are left off the run line, they are
not used and the STDOUT and STDERR go to the console.
If :out and :err are included, the STDOUT and STDERR
are captured and your Proc variable are populated
with their file handles.
So why leaving them out, does not the default shown
on line 232 apply?
