如何转换数字并在8086程序集中以视频图形模式显示它？

Question

我想知道如何在8086程序集中显示消息。

正如您在下面的代码中所看到的，我希望通过编写＆＃34; CONVERT＆＃34;来完成我的代码。程序。我如何填写此代码？

我应该在视频模式中的每个8像素中显示我的消息，这是一个字符的一个块。

CURSOR MACRO ROW,COLUMN ;key cursor
    MOV AH,02H
    MOV BH,00
    MOV DH,ROW
    MOV DL,COLUMN
    INT 10H
ENDM

DISPLAY MACRO STRING
    MOV AH,09H
    MOV DX,OFFSET STRING ;load string address
    INT 21H
ENDM

.MODEL SMALL
.STACK
.DATA
MESSAGE_1 DB 'PRESS ANY KEY TO GET OUT','$'
MESSAGE_2 DB 'THE MOUSE CURSOR IS LOCATED AT','$'
POS_HO DB ?,?, 'AND $'
POS_VE DB ?,?, '$'
OLDVIDEO DB ?
NEWVIDEO DB 0EH
