I have an array of hashes. What function should I be
using to interrogate each array cell when I want to
know if it is occupied?
"exists" seemed to do the job nicely. What about
"defined"?
Now I am curious: how would I implement a switch
statement (er, I mean, set of if-elsif statements) for
a hetrogeneous array where some array cells contain
arrays, others integers, other hashes?
I tried saying
my @x;
if(@x && $x[$ii] && %{$x[$ii]} && exists
$x[$ii]{"xyz"}){
my $z = $x[$ii]{"xyz"};
...}
But that did not work. There must be some function
that will tell me "this array cell contains a hash,
this other array cell contains another array...".
Thanks,
Sieg
