Exit command

Take a look at this:-

Graphics 640,480

Repeat
	Cls
	
	For Local column = 0 To 9
		For Local row = 0 To 19
			If row = 3 And column = 4 Then
				DrawText("row = "+row,0,0)
				DrawText("column = "+column,0,20)
				Exit
			EndIf
		Next
	Next
	
	DrawText("row = "+row,0,40)
	DrawText("column = "+column,0,60)
	
	Flip
	FlushMem
Until KeyDown(1)

I'm expecting

row = 3
column = 4
row = 3
column = 4

but my results are:-

row = 3
column = 4
row = 10
column = 20

Why does the exit command auto complete the remaining loop increments and not entirely break out of the loop?

Doh! I've already discovered the problem, just by reading through my own post. I forgot to add:-

If row = 3 And column = 4 Then Exit

in first for loop line. STUPID ME!

Move along now, nothing to see here. :)

Or you could do it like this:

Strict

Repeat
	Cls
	Local row, column
	#colsandrows
	For column = 0 To 9
		For row = 0 To 19
			If row = 3 And column = 4 Then
				DrawText("row = "+row,0,0)
				DrawText("column = "+column,0,20)
				Exit colsandrows
			EndIf
		Next
	Next
	
	DrawText("row = "+row,0,40)
	DrawText("column = "+column,0,60)
	
	Flip
	FlushMem
Until KeyDown(1)

[edit]Err...What Beaker said...[/edit]

Wow that's pretty neat. Is that # like a goto branch command?
Quite unusual that you have to position it at the beginning of your loops.

It's a loop label. Labels always start with # in bmax.

Yeah, but there's no End Loop sort of command. I'm amazed BMax knows where to jump out of both loops as to me that would jump back before the loops.

After a long discussion (do a search for it), this was the agreed compromise to the problem of Exiting multiple loops.

Cheers, interesting read that.

Had a bit of chuckle though when it ended with a fight :)
