This test seems to work:
Script of one button to load the array:
put "bob" into gA["bob"]
put "44" into gA["bob"]["age"]
put "ted" into gA["ted"]
put "48" into gA["ted"]["age"]
Script of a second button to split a key and use it to retrieve a value:
put fld "key" into s
split s by comma
put gA[s] into fld "r"
put the result
There are two fields - the one named "key" has:
...and when I click the second button the field named "r" shows:
Nothing shows in the Message Box, so presumably there was no error.
This is what I would expect, since associative arrays usually have no
way to distinguish between numeric and non-numeric keys, since all of
them are treated as strings when they go through the hash to assign
