Hi Josh,
Thanks for the response.
From the output below, I see that we do have the arrary elements with
the strings as index created. But, an extra array member is being
created for every multidimensional associative array.
$ echo "${.sh.version}"
Version JM 93u 2011-02-08
$ typeset -A foo
$ typeset -A foo[bar]
$ typeset -A foo[baz]
$ foo[bar][cat]=1
$ foo[bar][dog]=2
$ foo[baz][mouse]=3
$ foo[baz][fish]=4
$ set | fgrep foo
_='foo[baz]'
foo=([bar]=([0]='' [cat]=1 [dog]=2) [baz]=([0]='' [fish]=4 [mouse]=3) )
$
But with the alpha release, I don't see the extra element.
$ echo "${.sh.version}"
Version AIJMP 93v- 2013-10-08
$ typeset -A foo
$ typeset -A foo[bar]
$ typeset -A foo[baz]
$ foo[bar][cat]=1
$ foo[bar][dog]=2
$ foo[baz][mouse]=3
$ foo[baz][fish]=4
$ set | fgrep foo
_='foo[baz]'
foo=([bar]=([cat]=1 [dog]=2) [baz]=([fish]=4 [mouse]=3) )
$
So it looks to me that ksh93 does support the associative arrays with
more than one dimension.
Am I missing something here?
Thanks,

ksh93 does not support multidimensional associative arrays.
Only indexed multidimensional arrays are supported. If you wish to do
the same for associative arrays just append the strings.
The 12-08-20 issue you're referring to was a bug which tried to create
multidimensional indexed arrays using string as index, which are
equivalent to the arithmetic value 0 if they are not defined variables
yet and set -o nounset was not set.
Arguably the right fix here is that ksh93 should throw an error if
someone tried to use an associative array with more than one
dimension.
