What does the following assembly language program do? What is the result in DX register after the execution of the program?

Following this example, can you use branch structure to implement an assembly language program that will compare the contents of two word data in memory locations [DS:SI]=[3600H:1250H] and [DS:DI]=[3600H:1260H], and place the larger value of the two into memory location [DS:1270H]?

(2). What does the following assembly language program do? What is the result in DX register after
the execution of the program?
CMP AX, BX
JC
DIFF2
DIFF1: MOV DX, AX
SUB DX, BX ; (DX)=(AX)-(BX)
JMP DONE
DIFF2: MOV DX, BX
SUB DX, AX ; (DX)=(BX)-(AX)
DONE: NOP
