Hi guys,Please help me Confused

!I'm in the middle of a program,i want to know how can i return to previous loop that i want,for example:

Code:

Program 33333;

  Var

    i,j,k:integer;

Begin

  For i:=1 To 100 Do

    Begin

      For j:=1 To 100 Do

        Begin

          For k:=1 to 100 Do

            If {Something!...} Then

               {Here I want to go to the second For(with j counter)}

            Else

            .

            .

            .

What should I do?
P.S:I have read goto , break, label ,... instructions in Pascal's help but there was no advancement.
Thanks

I think that you need to go stop k loop, and that is by using "exit" command. So
the code should look like :

Code:

if condition then

exit;

Or by using go to and label.
You first declare label :

Code:

var

  label loop_j;

and then you make it in loop j like "loopj:"
and after condition, you just call it with go to :

Code:

if condition then

  goto loop_j;
