Write a data directive statement to define INIT_COUNT as word size and assign it the value F000H 20. Show how the segment-control directives are used to define a segment called DATA SEG that is aligned on a word-address boundary, overlaps other segments with same name, and is a data segment.Explanation / Answer
SUB A- subtract the contents of the accumulator A from the accumulator and the result will be stored in accumulator A.
After execution of the sub A instruction, the result stored in A is 0.
MOV CL, 0FFH is a one byte size instruction. The hexa decimal number 0FFH is moved to register CX.
