我需要使用汇编语言绘制(打印)堆栈和队列。任何人都可以使用VGA图形向我推荐代码吗?

我试图修改绘制(打印)矩形的代码。这就是我所做的:

DATA SEGMENT
       H DW 150
       W DW 30
       K DW 150     
       TEMP DW 0000
       TEMP2 DW 0000
       TEMP3 DW 0000    
DATA ENDS

CODE SEGMENT
    ASSUME CS:CODE,DS:DATA
  START :MOV AX,DATA
         MOV DS,AX

  START1:      
         MOV AH,00H
         INT 16H
         CMP AL,61H ;press a to close
         JZ END1
         CALL RECT

       RECT PROC
         MOV AH,0
         MOV AL,12H
         INT 10H

         MOV CX,W
         MOV DX,H
         MOV TEMP2,CX

         MOV BX,CX
         ADD BX,DX
         MOV TEMP,BX

         MOV AX,0C02H

  BACK:  INT 10H
         INC CX
         CMP CX,TEMP ;---top
         JNZ BACK

         MOV AX,0C30H

   BACK1:INT 10H
         INC DX
         CMP DX,CX ;--ver right
         JNZ BACK1

         MOV AX,0C02H

   BACK2:INT 10H
         DEC CX
         CMP CX,TEMP2 ;--bottom
         JNZ BACK2

         MOV AX,0C02H

   BACK3:INT 10H
         DEC DX
         CMP DX,CX ;--left
         JNZ BACK3

         MOV AH,07H
         INT 21H
         RET

         RECT ENDP

    END1:MOV AH,4CH
         INT 21H


    CODE ENDS
        END START

我已编码的堆栈程序是:

data segment 

 str1 db 0Ah, 0Dh,"CHOOSE OPERATION", 0Ah, 0Dh, '$'

 str2 db 0Ah, 0Dh,"P FOR PUSH",0ah,0dh,'$'

 str3 db 0A, 0Dh,"R FOR POP",0ah,0dh,'$'

 str8 db 0Ah, 0Dh,"D FOR DISPLAY",0ah,0dh,'$'

 str9 db 0Ah, 0Dh,"Any key for exit",0ah,0dh,'$'

 str4 db 0Ah, 0Dh,"Enter value to be pushed",0ah,0dh,'$'

 str5 db 0Ah, 0Dh,"Overflow",0ah,0dh,'$'

 str6 db 0Ah, 0Dh,"Do you want to continue? (y/n)",0ah,0dh,'$'

 str7 db 0Ah, 0Dh,"Empty stack",0ah,0dh,'$'

 str10 db 0Ah, 0Dh,"Popping..$"

 choose db 1 dup(0)

 top db 1 dup(0)

 temp db 1 dup(0)

 t db 1 dup(0)

 array db 100 dup(0)

 maxsize db 1 dup(0)
data ends

code segment

    assume cs:code, ds:data

    start: mov ax,data
