서로 다른 크기의 사각형을 인쇄하십시오.

Question

그래서 화면의 다른 영역에서 크기가 다른 사각형을 인쇄하는 작업이 있습니다. 각 사각형을 다른 사각형에서 똑같이 멀리 떨어지게하고 싶습니다. u로 볼 수 있듯이 각 사각형 사이의 거리가 항상 감소합니다. 나는 문제가 내가 lengthOFsideAX에를 업데이트 할 때, 변경되지 않는다는 것입니다 생각

: 이것은 내 결과입니다. 다른 팁은 많이 주시면 감사합니다 :) 여기에 코드입니다 : lengthOFside 5의 고정 된 값을 가지고 있기 때문에

; 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

    ; add your data here!
