/* In general, array references are resolved via a subroutine call.

|
* The array must be static, i.e. its element size and its index
|
|
* range must be static. In these cases the array descriptor will
|
|
* normally be stored in a rom and an element will be accessed via
|
|
* the sequence "lae lar", in which lae puts the address of the
|
|
* descriptor on the stack. The efficient method is used only if the

|
* element size is 2 or 4 bytes. We also make sure that
