This simple script shows:

• ksh88 limits the size to 2^12-1 (4095). (subscript out of range )

• ksh93 limits the size of a array to 2^22-1 (4194304)

• bash doesn't impose any hard-coded limit outside the one dictated by the underlying memory resources available. For example bash uses 1.3 GB for an array size of 18074340.
