It probably sits better with something like:

But 5.10 will (probably) introducde the // operator which will allow

$var //= 10;
Where do you get this insider information Paul? And what's this operator
going to do?

$var|=10; # like that if u want to set the variable to a default value--
# if the $var is not defined it assigns a value of 10 to it.

You need to use the ||=
perhaps such a statement would suit:
$var = defined $var ? $var : 10;

Hi guys,
How can I get around this warning
Use of uninitialized value in pattern match (m//) at test.pl line 85.
For some reason I always get driveNum=2.
I am using warinig and strict in my code..
code
if ($pong-ping($mslRef{$server}{ip})) {
#check for 2 drives
C:\WINNTperldoc -q warnings
Found in C:\Perl\lib\pod\perlfaq7.pod
How do I temporarily block warnings?
If you are running Perl 5.6.0 or better, the use warnings
pragma allows fine control of what warning are produced. See the
perllexwarn manpage for more

Hi Chad,
Please send your code again with line 85 marked. You have that information in front
of you, while we are at a disadvantage.
Thanks,
