Make a detailed trace of the execution of the following program fragment, giving the contents of all the registers, and memory locations involved. Assume that before execution begins the SS register contains 0210h, and the SP register 0100h, and that the contents of AX, BX, CX, and DX are 2143h, 0100h, 1BEFh, and 9A78h respectively.

		SS	SP	TOS	AX	BX	CX	DX
Initial contents		0210	0100	/	2143	0100	1BEF	9A78
after	PUSH AX
after	PUSH BX
after	PUSH CX
after	POP DX
after	POP CX
after	PUSH DX
after	POP AX
after	POP BX

Any explanation I would appreciate it. I want to learn how it is done.
