Why don't you try running it?
| Code: |
Procedure Division.
Perform SectionA.
Display 'After Perform'.
SECTIONA.
Display 'inside SECTIONA'.
|
Please let us know the result after you execute it.  |

| after the return to the display command, then you will drop thru section a till you hit the stop run (which you should make - goback). |

for me the output coming is
INSIDE SECTIONA
I didn't expect that ... I thought that the output would be:
INSIDE SECTIONA
AFTER PERFORM.
why is it behaving like this?? |

STOP RUN stops the run unit.
GOBACK returns to caller, whether program, mvs or whatever. |

since you did not post your code (where is the SECTION. statement?) sorta hard to determine what you have and why. Looks like you are performing paragraphs and do you have a go to anywhere?
no more questions, post the code....................... |

There are no sections in the posted code.

Not from the posted code. . .
Is there actually a question at all? As DBZ says "post the code................." |

Procedure Division.
Perform SectionA.
Display 'After Perform'.
SECTIONA.
Display 'inside SECTIONA'.
When I ran the above code I got:
INSIDE SECTIONA

Doesn't COBOL generate an implicit GOBACK at the end of the a program?
Won't "END OF SECTIONA" generate a syntax error, and possibly just be ignored?
What kind of paragraph name is SECTIONA? Somewhat confusing, isn't it?
Is it time for this to fall into the OT hole? |

Well,
Your first post
| Code: |
Procedure Division.
Perform SectionA.
Display 'After Perform'.
SECTIONA.
---------
---------
---------
---------
END OF SECTIONA.
STOP RUN. |
Your expected output is
| Quote: |
INSIDE SECTIONA
AFTER PERFORM. |
I assume when you say "output", you actaully taking about DISPLAY statements of your program; if so
was never DISPLAYed in your above code, the output you got
is confusing.
Per your second code, the expected output make a little sense but are you sure there is no other PERFORM SECTIONA in your program. And if only one PERFORM then where do you 'instruct' the program to 'stop', as asked earlier where do you code, GO BACK or STOP RUN.
BTW, SECTIONA is not a good choice for para-name; SECTIONs have different meaning in COBOL. |

No I think it doesn't happen. Ran a program without GO BACK (or STOP RUN), program was abended with ABEND=S000 U4038 REASON=00000001
with the following message in SYSOUT
| Quote: |
| The flow of control in program TESTPGM proceeded beyond the last line of the program. |
While the same program executes well with GO BACK. |

Once again I'm in..
Tried the below codes:
| Code: |
PROCEDURE DIVISION.
PERFORM 0000-PARA.
DISPLAY"AFTER PERFORM".
0000-PARA.
DISPLAY"INSIDE PARA".
GOBACK. |
SYSOUT:
And the other code is:
| Code: |
PROCEDURE DIVISION.
PERFORM 0000-PARA.
DISPLAY"AFTER PERFORM".
GOBACK.
0000-PARA.
DISPLAY"INSIDE PARA". |
SYSOUT:
| Code: |
INSIDE PARA
AFTER PERFORM |
Check the positions of GO BACK.
Hope this helps. |

Possibly the same homework assignment. . .?
And if the "lesson" was actually about SECTIONs, the point was entirely missed. . .

Hi D.Sch,
The new code (with an additional display statement) that I tried is:
PROCEDURE DIVISION.
0000-MAINLINE.
PERFORM SECTIONA.
DISPLAY 'AFTER PERFORM'.
SECTIONA.
DISPLAY 'INSIDE SECTIONA'.
DISPLAY 'GOING BACK'.
GOBACK.
0000-EXIT.
EXIT.
My new sysout is:
INSIDE SECTIONA
GOING BACK |
