Fill using Drawline.

[MossyMossy]

Turing:

var point1r, point1c : int var point2r, point2c : int var point3r, point3c : int var point4r, point4c : int put "please enter your first row and first coloumn" get point1c point1c:= point1c *10 get point1r point1r:= point1r *10 put "please enter your second row and second coloumn" get point2c point2c:= point2c *10 get point2r point2r:= point2r *10 put "please enter your third row and third coloumn" get point3c point3c:= point3c *10 get point3r point3r:= point3r *10 put "please enter your fourth row and fourth coloumn" get point4c point4c:= point4c *10 get point4r point4r:= point4r *10 cls %%%%%%%%% % x1,y1,x2,y2 % % x3,y3,x4,y4 % % x4,y4,x1,x1 % % x2,y2,x3,y3 % %%%%%%%%% drawline(point1c,point1r,point2c,point2r,5) drawline(point2c,point2r,point3c,point3r,5) drawline(point3c,point3r,point4c,point4r,5) drawline(point4c,point4r,point1c,point1r,5) %%%%%%%%%%%% % This is the problem i am having. Cannot get the row's to loop so it fills in with draw lines. loop point1c:= point1c +1 drawline(point1c,point1r,point2c,point2r,green) exit when point1c >= point2c point2c:= point2c +1 drawline(point1c,point1r,point2c,point2r,green) exit when point2c >= point1c end loop

What im trying to do is fill it in using Drawline. so i have to fill it in with a loop that i atempted above. so it crosses row's, then another loop were it crosses the coloumns, so it fills in using draw line.

Its simple but I cant get the draw line with the loop to work, it displays a failed outline.


Please help.

Thanks.

*also to make the box, enter the 1st 2nd 3rd 4th as.

10
10
10
20

to form a box.

If I enter box co-ordinates 10/10/10/20/...

What does point1c >= point2c in

code:

exit when point1c >= point2c

evaluate to, the first time it's checked?

How many times does the loop execute?
