異なるサイズの四角形を隣り合わせに印刷する

Question

私は、異なるサイズの四角形を画面の異なる領域に印刷するタスクを持っています。私は、各正方形が他の正方形から等しく離れているようにしたい。あなたが見ることができるように、各広場間の距離は常に減少します。私は、問題は私がlengthOFsideAXにを更新するとき、それは変更されないということだと思います

：これは私の結果です。その他の先端ははるかに高く評価されます:)ここではコードです：lengthOFsideは5の固定値を持っているので

; multi-segment executable file template.  

newline=160 ;number of chars to move to next line 
col = 2  ;each column is another charachter 
lengthOFside = 5 ;side of square, grows each time of the loop 
numRow = 5 ;which row to start from 
numCol = 30 ;which col to start from 
numSquares = 4 ;number of squares 


data segment 
    ; add your data here! 
    pkey db "press any key...$" 
ends 

stack segment 
    dw 128 dup(0) 
ends 

code segment 
start: 
; set segment registers: 
    mov ax, data 
    mov ds, ax 
    mov AX,0B800H 
    MOV ES,AX 



    ; add your code here 

    ;first print 


    MOV DH, numSquares  ;number of squares I want to print 
    MOV AX,lengthOFside  
    MOV BL,numRow ;number line 
    MOV BH,numCol ;num col 
    MOV CX,lengthOFside ;length of one side 
    CALL print_square ;CALL the function that prints the square 
    DEC DH 


    loopPrint: 
    lengthOFside = ax 
    ADD BH,lengthOFside+2 ; move right lengthOFside times. 
    ADD AX,2 
    MOV CX,AX 
    CALL print_square ;print square 

    DEC DH 
    jnz loopPrint 





    lea dx, pkey 
    mov ah, 9

    ; wait for any key....  
    mov ah, 1

end start ; set entry point and stop the assembler. 

Answer 1

ADD BH,lengthOFside+2 ; move right lengthOFside times. 

はこれ常に右に同じ量を移動します！

add  bh, al 
add  bh, 2 
add  ax, 2 

短い：

add  ax, 2 
add  bh, al
