hm. I assumed it did an implied close once the command was done executing.
once i do an explicit close, $? gets the exit value.
thanks everyone who answered this thread.

If I open a pipe on a command that has a nonzero exit status,
where do I check that???
close($HANDLE2);
after the read loop in order to get its correct exit status.
If you really want to be thorough, do
my $r = close($HANDLE2);
and look at $r to determine whether you even need to look at $?, etc.
man perlfunc#open for details and other useful bits.
