I have forgot that, is there a //= operator in Perl?
which should do the same stuff as:
unless (defined($foo) ) {
$foo = ...;
}
Thanks.

Hi,
when I put this line in a script say a.pl:
#!/usr/bin/perl -wl
...
And later I run it from the command line:
perl a.pl
so, does this make perl ignore the "wl" switch in the script?
Thanks.

does "return ()" mean return an empty list, or just mean "return" since "()" is
optional in Perl?
thanks!

hello,
when in the case "return undef" I prefer just "return" coz in list context it
will return an empty list.
my $exist = ...
if ($exist) {
return 1;
} else {
return;
}
the code above can work, but having many lines.
So I want:
return $exist ? 1 : (...);
what should be put in (...)

Have you set the "Disposition" option to "attachment" rather than the default
