Hi,
I have a small code like below. I saved this into a file named as: ./test.pl
If we run this code without using the option -libFile like this:test.pl -test true it writes out the message:Can't use an undefined value as an ARRAY reference at ./test.pl line 14.
How should I initialize
$lib on
Line 7? I tried setting it to an empty array but it did not help.
Kindly help!
Robert
