; for(i=0; i < N; i++)
; Array1[i] = 0;

Addressing mode (see Chapter 5)
Immediate constant value of zero
Load the location pointed to by the "loc16" addressing mode with the value
0x0000:
[loc16] = 0x0000;
If (loc16 = @AX), then the load to AX is tested for a negative condition. The
negative flag bit is set if bit 15 of AX is 1, otherwise it is cleared.
If (loc16 = @AX), then the load to AX is tested for a zero condition. The bit is
set if the result of the operation on the AX register generates a 0 value,
otherwise it is cleared.
This instruction is repeatable. If the operation is follows a RPT instruction,
then it will be executed N+1 times.
