How to come out of loop after x iterations.

Hi Guys

 I am writing a skill code for for loop.Which executes statements  for 10 iterations.

I am keeping a check point at 8th iteration loop,and i want to come out of the loop,if my condition is satisfied.

I don't want to come out of my program,only come out of for loop only.

 Pls let me know ?

 Thanks and regards

     First thing you could do is to just use a while loop instead:

    count=1 finished=nil while(count<=10 && !finished println(count) when(count==7 finished=t) count++ )
    Or you could use the prog() construct to allow you to return early:
    prog(() for(count 1 10 println(count) when(count==7 return()) ) ; for ) ; prog

    Personally I don't tend to like using the prog() approach - it leads to "spaghetti programming" where you've effectively got hidden jumps out of the code in the middle, which makes the flow of the program harder to understand.

    Regards,

    Andrew.

    Hi Andrew

     

    Thanks a lot,It works fine.

    Both are quite good.But in my way we can prefer prog method,i thinks so.

     

    Thanks and regards
