Hi,

Can we use depending on like this. I have given the declaration
Code:
01  WV-OUT-PARM1.                                     
    05 WV-REG-CODE1             PIC X(02).             
    05 WV-REG-OPEN-CNT1         PIC 9(05).             
    05 WV-REG-SUB-CNT1          PIC 9(05).             
    05 WV-DISTRICT1             OCCURS 1 TO 20 TIMES     
                                           DEPENDING ON WV-DIST-MAX
                                           ASCENDING KEY IS WV-DIST-CD1
                                            INDEXED BY WV-DIST1-IDX .   
       10 WV-DIST-CD1           PIC X(02).             
       10 WV-DIST-OPEN-CNT1     PIC 9(05).             
       10 WV-DIST-SUB-CNT1      PIC 9(05).             
       10 WV-DEALER1            OCCURS  1 TO 40 TIMES   
                                            DEPENDING ON WV-DLR-MAX
                                           ASCENDING KEY IS WV-DLRT-CD1
                                            INDEXED BY WV-DLR1-IDX.   
          15 WV-DLR-CD1         PIC X(05).             
          15 WV-DLR-NAME1       PIC X(30).             
          15 WV-STATUS-CD1      PIC X(02).             
       10 WV-FILLER1            PIC X(01).             



After fetching from db2 tables, I am moving the fetched values to these declarations. I ran the sql seperately and that fetching eight values.


My problem is I am not getting the wv-dlr-cd1, dlr-name1 , status-cd1 values in order. For ex , for the first to seven indexes I am not getting any wv-dlr-cd1, dlr-name1 , status-cd1 values and for the last eighth index alone I am getting values.

Can anyone suggest me whats wrong in this. When I displayed the wv-dlr-cd1, dlr-name1 , status-cd1 values seperately, I am able to see . But when i tried to display as group item WV-OUT-PARM1., I am not able to see that. Please suggest me.

In what order? When are you setting the indexes?

hi,

Before move I am setting both the indexes to one. It should be in fetched order. The values should be in order as fetched but for me there are no values for first seven indexes, When i displayed as group item. The values are there from eighth index.

I think the values are relocated. The problem is in depending on WV-DIST-MAX and WV-DLR-MAX. When I remove the depending on clause, I am getting the values in order.

It would help to see the actual move statements -- complex ODO structures like this are easy to get wrong.

what values do you populate in WV-DIST-MAX and WV-DLR-MAX?

when do you populate them?

HI,

I am not using that in this program. Usually I can use that wv-dist-max for some process. For ex. set wv-dist-max =1
perform para1 until wv-dist1-indx = wv-dist-max.

I have to declare like that. Thats the must in our pgming guidelines.

Hi,

Little changes in prev post. After fetch, the max will be automatically set. So I can use wv-dist-max like this. For ex. set wv-dist-indx =1
perform para1 until wv-dist-indx = wv-dist-max.

Suggest me what wrong in the code.

show us the code you use to load the tables.

stop showing us little things that you want to share. you have a problem, show us the code. we can then try to help.

stop determining what we need to see. if you knew, you would not need our help and be hopelessly going around in circles.

Hi,
Code:
PERFORM UNTIL WV-END-OF-CSR                                 
  IF STATUS-CD OF BTC04430 NOT = '40'                       
   IF DSTRCT-CD OF  BTC02090   =  WV-DIST-CODE               
      MOVE DLR-CD OF BTC02010     TO                         
                    WV-DLR-CD1 (WV-DIST1-IDX,WV-DLR1-IDX)   
      MOVE DBA-NM OF BTC02010     TO

 END-PERFORM.                                                                                   

I have given the code. Please suggest me .

Hello,

Is the code presented as it actually is in the program? What is posted does not appear to have continuity (i may be mis-reading something). It is not clear what values will be in the indexs as they are used/incremented.

Suggest you map out your process on paper and "play computer" with some sample data.

You might want to put some displays in the code to show which table entries are being referenced as the code is executed. You would only need to process a very small amount of data for this test.

Unless I'm missing something, you have an unmatched IF statement in your code. Does this compile successfully?

Code:
PERFORM UNTIL WV-END-OF-CSR                                 
  IF STATUS-CD OF BTC04430 NOT = '40'                       
   IF DSTRCT-CD OF  BTC02090   =  WV-DIST-CODE               
      MOVE DLR-CD OF BTC02010     TO                         
                    WV-DLR-CD1 (WV-DIST1-IDX,WV-DLR1-IDX)   
      MOVE DBA-NM OF BTC02010     TO                         
                    WV-DLR-NAME1 (WV-DIST1-IDX,WV-DLR1-IDX)
      MOVE STATUS-CD OF BTC04430  TO                         
                    WV-STATUS-CD1 (WV-DIST1-IDX,WV-DLR1-IDX)
      SET WV-DLR1-IDX  UP BY +1                             
   ELSE 
1. As Terry says, you've got more IF than END-IF statements.
2. You use WV-DIST1-IDX and WV-DLR1-IDX without bothering to tell us how they are set.
3. You increment WV-DLR1-IDX without bothering to check for hitting the boundary.
4. You increment WV-DLR1-IDX without letting us know the value of WV-DLR-MAX, nor do you increment the value of WV-DLR-MAX before incrementing WV-DUR1-IDX. If WV-DLR1-IDX exceeds WV-DLR-MAX the results of your MOVE statements is suspicious at best, possibly dangerous to your data at worst.
5. WV-DIST-MAX must be carefully controlled or you will invalidate your table. Incrementing WV-DIST1-IDX past WV-DIST-MAX will definitely cause you problems.

From the Programming Guide:
Quote:
Be careful if you reference a complex-ODO index-name, that is, an index-name for a table with variable-length elements, after having changed the value of the ODO object for a subordinate data item in the table. When you change the value of an ODO object, the byte offset in an associated complex-ODO index is no longer valid because the table length has changed. Unless you take precautions, you will obtain unexpected results if you then code a reference to the index name such as:

* A reference to an element of the table

* A SET statement of the form SET integer-data-item TO index-name (format 1)

* A SET statement of the form SET index-name UP|DOWN BY integer (format 2)
