| Code: |
IF RMF-RS-SECTION-ALPHA (RMF-VCA-SECTION-CNTL-INDX)
MOVE '1' TO NQA-SW
MOVE 99 TO RMF-VCA-SECTION-CNTL-INDX. |
will this work??
| Quote: |
RMF-RS-SECTION-ALPHA (RMF-VCA-SECTION-CNTL-INDX) returns a string |
when will this condition fail??
Please help. |

what is the data definition of RMF-RS-SECTION-ALPHA?
and COBOL does not deal with strings. |

Dick Brenholtz ,
Here is the definition.
| Code: |
20 RMF-RS-SECTION-TABLE OCCURS 99.
25 RMF-RS-SECTION-ALPHA PIC X(03). |
This is my production code, am analyzing this code. |

1. what cobol compiler was used to compile this production code?
2. where did the quote come from?
| Quote: |
Quote:
RMF-RS-SECTION-ALPHA (RMF-VCA-SECTION-CNTL-INDX) returns a string
|
actually the above addresses a 3 byte field defined as alphanumeric.
'returns a string' is verbiage applied to a function or method,
both of which the indexed Reference is not.
something else is going on, because the IF statement should not have compiled under ibm COBOL II or ibm E-COBOL.
are there any entries in the SPECIAL NAMES section? |

I guess the condition is always true, cause you get a string or spaces what
is also a string returned. |

Peter,
could you explain why this would be true? why it would even compile? |

Dick Brenholtz,
Am not sure.
The code is written some 20 years back.
Special names section is not mentioned. |

Dick,
to be fair, I was thinking in C where string functions return a pointer
or NULL. So i assumed that today cobol has string functions too.
My latest cobol experience is about 30 years ago, so it maybe better to
refrain from cobol topics. |

These things are not hard to test yourself, you know. If you put this into a program and attempt to compile it, you get
| Code: |
IF RMF-RS-SECTION-ALPHA (RMF-VCA-SECTION-CNTL-INDX)
IGYPS2096-S An incomplete condition was found in a conditional expression. The
operand(s) was(were) discarded. |

Ya I knew I will get the error but still it is in my production module and it is working.
Is it possible in previous versions of cobol??
Because as i said the code was written 22 years back.
Now, am using Cobol-II. |

Robert has proved that the code snippet will not compile.
to continue the theoretical discussion -
since this code is in production,
obviously it compiled - sometime in the distant past
we need the 'enveloping' code.
it it appears to be part of a perform varying
(since the code modifies the subscript).
shankarm,
could you post the code that invokes the code snippet that you showed.
also, your quote about the returned string,
who told you that? |

Folks,
Sorry for the delay.
I have some problem with my ID.
I am not able to logon to mainframe.
I ll paste the code once my logon issue is solved(in few mins). |

Guys here is the code..
| Code: |
C100-BD-VALIDATE.
MOVE 0 TO ERR-HLD1.
**** STA-BA IS OVERRIDE FOR SAA-L, -J, -2 ************
IF P-PRES-IND(STA-BA) = 'Y'
IF P-PRES-IND(SAA-L) NOT = 'Y'
IF P-PRES-IND(SAA-J) NOT = 'Y'
IF P-PRES-IND(SAA-2) NOT = 'Y'
MOVE 2469 TO ERR-HLD1
MOVE P-SCAN-SUB(STA-BA) TO HLD-SUB1
MOVE 'STA' TO SRCH-KEY
PERFORM D000-ERR-LOAD THRU D000-EXIT
********************************************************
* THIS CODE COMMENTED OUT AS PER GARY GOODNUFF 3/8/89.
********************************************************
* IF RMF-GAA-A-FLAG = 'Y'
* IF P-PRES-IND (WAA-M) NOT = 'Y'
* MOVE 2258 TO ERR-HLD1
* MOVE P-SCAN-SUB (GAA-A) TO HLD-SUB1
* MOVE 'GAA' TO SRCH-KEY
* PERFORM D000-ERR-LOAD THRU D000-EXIT.
MOVE 1 TO RMF-VCA-SECTION-CNTL-INDX.
MOVE '0' TO NQA-SW.
C100-BD-NQA-CHK.
IF RMF-RS-SECTION-ALPHA (RMF-VCA-SECTION-CNTL-INDX)
MOVE '1' TO NQA-SW
MOVE 99 TO RMF-VCA-SECTION-CNTL-INDX.
ADD 1 TO RMF-VCA-SECTION-CNTL-INDX.
IF RMF-VCA-SECTION-CNTL-INDX > RMF-RS-SECTION-COUNT
NEXT SENTENCE
ELSE GO TO C100-BD-NQA-CHK.
IF P-PRES-IND (FFA-N) = 'Y'
IF ((P-PRES-IND (FSA) NOT = 'Y') AND
|
and goes on...
the calling module is
| Code: |
IF RMF-KA-REPORT-TYPE = 'BD'
PERFORM C100-BD-VALIDATE THRU C100-EXIT
|
This callin module is inside another perform.. and that inside another... but nothing in perform varying loop. |

MOVE 1 TO RMF-VCA-SECTION-CNTL-INDX. |
the code commented out as per gary goodnuff 3/8/89
removed the only period '.' (end of if statement)
thus causing the period after
MOVE 1 TO RMF-VCA-SECTION-CNTL-INDX.
to end the (typical 20-year old BS) IF statement.
also, the move will only be executed if all four IF's are statisfied
otherwise RMF-VCA-SECTION-CNTL-INDX is never reset.
afterwards, the logic falls thru this garbage:
| Code: |
MOVE '0' TO NQA-SW.
C100-BD-NQA-CHK.
IF RMF-RS-SECTION-ALPHA (RMF-VCA-SECTION-CNTL-INDX)
MOVE '1' TO NQA-SW
MOVE 99 TO RMF-VCA-SECTION-CNTL-INDX.
ADD 1 TO RMF-VCA-SECTION-CNTL-INDX.
IF RMF-VCA-SECTION-CNTL-INDX > RMF-RS-SECTION-COUNT
NEXT SENTENCE
ELSE GO TO C100-BD-NQA-CHK.
|
the next time thru C100-BD-VALIDATE
the value of RMF-VCA-SECTION-CNTL-INDX will be 99.
depending on if the aforementioned set of nested IF's.
Good Luck with this crap.
so you have two problems:
1. what was this incomplete IF really meant to be
2. correct the missing . |

Hi,
I have one question - Is it possible that, when this particular production code was moved, the load module did not refresh and was having same old load module.
Also, is it possible or are there any ways by which i can check whether a given statement is part of load module? |

Depending upon how the move was done, it is possible that the load module was not refreshed -- but most of the time the production control group is aware of the possibility and is very careful to ensure the move actually did occur. An AMBLIST on the load module should resolve any doubts, one way or the other -- as long as you know the date of the move.
And as far as your second (of one) question, while there are some special circumstances in which source code is associated with load modules (such as compiling with products that allow source analysis of executions), in general you cannot determine which COBOL source statements were compiled to create a particular load module. |
