Here, i have included coding part. Can anyone give the answer?
will the control back to para-1 if i execute goto statement????

Program:

Perform para-1 thru para-1-exit.
para-1.
Move 1 to ws-count
Display 'aaaa'
Goto para-2
para-1-exit.
Exit.

para-2.
Display 'bbbb'.

Select all

Perform para-1 thru para-1-exit.
para-1.
       Move 1 to ws-count
       Display 'aaaa'
       Goto para-2
para-1-exit.
       Exit.

para-2.
       Display 'bbbb'.

No, whatever is after para-2 will be executed...
If nothing is after para-2, an implicit stop run/goback will take place.

Suppose if there is an 'DISPLAY "cccc"' statement after GOTO statement, will 'cccc' displayed or not?

Ajith Kumar,
Did you tried running your code? You have given the code, then why are you hesitating to run that? Try that and let us know.

Of course not, why would you even think it might?

Perform cannot contain goto because goto takes the control out of the perform and the control is not returned back.So in your case the control will never come back to para1..To chk ths jus give a display statement in para-1-exit and chk out..Correct me if am wrong pls..

A rather broad statement.....and not entirely correct.....
If the perform was in the paragraph through paragraph form, the 'go to'ed branch could return to a paragraph within the preformed loop....

Hello,

There is also often a big difference between what the compiler will allow and what is good programming practice. . .

FWIW, usually the only 'GO TO's I've seen have been to an abend routine or an EOJ routine.....
