Hash: SHA1
Hi all,
I have a small question about using a scalar reference contained in a hash
:
Here's an example :
$a=5;
%zzz = { v => \$a};
$b=$zzz->{v};
print "Before A: $a\tB: $$b\n";
$$b++;
print "After A: $a\tB: $$b\n";
this code prints :
Before A: 5 B:
After A: 5 B: 1
while the output I expect is like in the 2nd snippet
Before A: 5 B: 5
After A: 6 B: 6
$a=5;
$b=\$a;
print "A: $a\tB: $$b\n";
$$b++;
print "A: $a\tB: $$b\n";
What's my problem with the hash ?
Regards,
Fred.
