Practical training assembly language design-16-digit split into 4 groups

Practical training: In ax, 16 digits are divided into 4 groups (1234 divided into 1, 2, 3, 4), each group with 4 digits placed in Al, BL, Cl, DL

A:

Data Segment

Data ends

Cseg segment

Assume Cs: cseg, DS: Data

Start:

MoV ax, 1234 H

MoV cl, 4

MoV dx, ax

And dx, 0fh

MoV BX, ax

Shr bx, Cl

And BX, 0fh

MoV CH, BL

MoV BX, ax

Shr bx, Cl

Shr bx, Cl

And BX, 0fh

SHR ax, Cl

SHR ax, Cl

SHR ax, Cl

And ax, 0fh

MoV Cl, CH

And CX, 0fh

MoV BH, BL

MoV DH, DL

MoV DL, Al

Add DL, 40 h

MoV ah, 2

Int 21 h

MoV DL, BH

Add DL, 40 h

MoV ah, 2

Int 21 h

 

MoV DL, Cl

Add DL, 40 h

Int 21 h

MoV DL, DH

Add DL, 40 h

Int 21 h

MoV ah, 1

Int 21 h

Exit:

MoV ah, 4ch

Int 21 h

Cseg ends

End start

Output: ABCD (corresponding: Al = 01 H, BL = 02 h, CL = 03 h, DL = 04 H)
