To exit from a loop

Former Member — Thu, 13 Oct 2005 06:56:20 GMT

Dear all,

The structure of my code is as follows :-

LOOP AT ITAB. (1)

.....

....

DO. (2)

....

DO. (3)

....

IF I > 2.

....GOT TO NEXT LOOP PASS (1).

ENDIF.

ENDDO.

ENDLOOP.

Which statement can I use to get out of the two DO loops and go to the next Loop pass of LOOP (1).

Please suggest.

Thanks in advance,

Archana

Hi Archana!

Easiest way: make a flag for this:


data next_loop type xflag.
loop at itab.
  clear next_loop.
  do.
    do.
      if ...
        next_loop = 'X'.
        exit. (3)
      endif.
    enddo.
    if next_loop = 'X'.
      exit.   (2)
    endif.
  enddo.
  if next_loop = 'X'.
    continue. (1)
  endif.
  ... (optional coding)
endloop.

Regards,

Christian

Hi Archana,

There is not one statement to get out of the innermost DO-loop and the outermost DO-loop at once.

You will have to program 2 consecutive EXITs (one for each DO-ENDDO) to accomplish this.

Hi Archana,

You can use CONTINUE to come out of the current loop.

see below example i hope it may help you.

DO 100 TIMES.

IF SY-INDEX >= 10 AND SY-INDEX <= 20.

CONTINUE.

ENDIF.

...

ENDDO.

if solution is helpful kindly reward the points

Hi,

U can use EXIT or STOP Statement.

Simple example of a DO loop:

DO.

WRITE SY-INDEX.

IF SY-INDEX = 3.

EXIT.

ENDIF.

ENDDO.

The output is:

1 2 3

There is no single staemant you can use - you can EXIT to extr to DO-LOOP. But to go to the next LOOP you have to use CONTINUE.

Define a help-variable ex. l_exit and set this to TRUE if you want to exit and check for this.

Hi!

The idea is the following - place DO(2) and DO(3) loops inside separate FORMS and handle return parameters from them bottom-up.
