For help, questions about the assembly language JMP instruction ~-CodePudding

See on assembly materials example:

Mov ax, 0123 h
Mov ds: [0], ax
Mov word PTR ds: [2], 1
JMP dword PTR ds: [0]

After the instruction execution, (CS)=0, (IP)=0123 h, CS: IP points to 0000:0123

Validate the, here's why value is 0 (CS)?

CodePudding user response:

Write wrong, should be ds: the [0002], 0 or 1, the two should be the same,

CodePudding user response:

reference 1/f, zara's reply:

write wrong, should be a ds: the [0002], 0 or 1, the two should be the same,

, write wrong, is mov word PTR ds: [2], 0
