case sensitivity of the keys in an associative array

[francois.chaplais]

Dear list

From my current work on a LiveCode project, it seems that the keys of an associative array are not case sensitive.

For instance, I may define 
theArray[« Ddt »]

If I define now  
theArray[« ddt »]

this entry replaces the previous one (forgive apple mail which replaces my double quotes by french double quotes)

Is this behavior confirmed?

Best regards
François
