According to the docu ptr should be pointing to the value or NULL.

PTR is pointing to NULL if the key isn't present in the array - but where
is it pointing to if the key is present?

Am I missing something?

D:\D\src\temp>keyin
&value:      12ff18     1
&array[key]: 870fd4     1
ptr:         870fd0     4264064
ptr:         870fd4     1

The first thing I thought was, when you add an 'int' to an array it copies  
the int creating a new one, so &value wont == &array[key], BUT, ptr should  
== &array[key].

My results seem to show that it's out by 4 bytes, 32 bits, or 1 int.

"InExpressions now, instead of returning a bit, return a pointer to the
associative array element if the key is present, null if it is not."

Looks like Walter forgot to check it. Looks like an implementation
thing, like it points to the hash of the key or something.
0x00411080 (*ptr in hex) does look like a string literal hash...
