Dermot :
Hi All,
I am unsure if the following statement is going to do what I want.
I want to test if there is a value in $hash_ref{'someval'} NOT if the
key is defined. I'd also like to avoid un-sightly "undefined value"
errors.
So which of the following is best:
if (defined($hash_ref{'someval'}) {}
I may think this is the better way.
also you can check perldoc -f exists and find something like:
print "Exists\n" if exists $hash{$key};
print "Defined\n" if defined $hash{$key};
print "True\n" if $hash{$key};
