The maximum number of variables is 32,768 (2**15).  It is the largest
integer that can can be held in an integer*2 variable.

The maximum number of cases is 2,147,483,648 (2**31). It is the largest
integer that can can be held in an integer*4 variable.



Limitations are more likely to arise from your memory (RAM)  and storage
(disk) capacity.

Hope this helps.
