Question about for .. next

[Arnold]

Hi Charles,

in Oxygenbasic I can use exit for leaving a do while block. Obviously I can use goto in a for loop, for example:

Code: OxygenBasic

1. 'Exit for .. next loop
2.  
3. include "$\inc\console.inc"
4.  
5. dim array[100]
6.  
7. for z = 1 to 3
8. for y = 1 to 10
9. For x=1 to 100
10.   if x = 55 then goto 1200
11.   array(x)=x
12. next x
13.  
14. 1200: print x " "
15. if y = 5 then print cr: goto 1500
16. next y : print cr
17.  
18. 1500: print y cr
19. for n = 1 to 100: print array[n] " ": next : print cr
20. next z : print cr
21.  
22. print x " " y " " z cr
23.  
24. waitkey()
25.  

this gives the expected results, I only would like to ask if this method is proper or if I should use a different approach? I also tried to jump into another 'for next' loop, but this happily did not work.

you can use exit for

Hi Roland,

You can jump from an inner block to an outer block but not vice versa. This is because inner block labels are not visible to outer blocks, and when a block finishes, its inner labels are forgotten.

There is no problem jumping out of loops , using exit or goto or jmp / jmp fwd
