I have a variable in my script that is taking on a value from a hash:
my $myvar = $hashname{$key}{$subkey}{in};
Where $hashname{$key}{$subkey}{in} may have never been assigned a value. I
later try to use $myvar (I use strict and warnings), and get an error "Use
of uninitialized value in ..."
I want to test $myvar immediately after the assignment to see if it is
uninitialized. I then get the same error on my conditional.
I have tried a few things, checked the Camel book and the Cookbook, and
tried to find something with my rudimentary knowledge of perldoc. I'm
guessing/hoping that there is a test for uninitialized. Please point me
towards the correct answer in any of the listed resources.
Thanks,
