我是一名初学者，看不懂程序，大家帮我看看这是什么意思，在界面怎么操作
currentstep=1
*DIM,Pos1,ARRAY,2,max_x*max_y
*DO,J,1,max_y,1
*DO,I,1,max_x,1
*IF,currentstep,EQ,1,THEN
Pos1(1,currentstep) = V1x/2-V2x/2
Pos1(2,currentstep) = V1Y
currentstep=currentstep+1
*CYCLE
*ENDIF
*IF,I,EQ,1,THEN
Pos1(2,currentstep)=Pos1(2,currentstep-1)+lysize
Pos1(1,currentstep)=V1x/2-V2x/2
*ELSE
Pos1(1,currentstep)=Pos1(1,currentstep-1)+lxsize
Pos1(2,currentstep)=Pos1(2,currentstep-1)
*ENDIF
currentstep=currentstep+1
*ENDDO
*ENDDO
