Hi All,
I am writing a COBOL,DB2,CICS program to implement pageup & page down logic. I have written pseudo conversational program. Before sending the map first time, I have loaded TSQ with all records from cursor and few records to the output variables of symbolic map. I am maintaining a counter vairable which is calculated while fetching data from cursor. This value is getting initialized to zero after send return of map.
Please advice me how to retain value of this variable.
I tried to retain this value, by declaring this varable in DFHCOMMAREA, but I am getting ASRA(SOC4) abend.
Also I tried to retain this value by declaring this variable in working storage commarea section which is used in COMMAREA of Return command. Still this value is getting initialized to zero.
Please advice me on this...
Thanks

Since you posted no code, what do you expect us to be able to do?
The way to retain values in a pseudoconversational CICS program is to place them in an area of WORKING-STORAGE (if using COBOL) and use that WORKING-STORAGE area as your COMMAREA( ...) in the RETURN TRANSID command. If this is not working for you, you have coded something wrong or are otherwise not conforming to the CICS API. We have no way to tell what you are doing wrong based upon what you have provided. |

Hi,
Below is the code to acheive the Page up, Page Down logic. I am trying to retain the value of the WS-CNT. But this value is getting initialized to zeros one send return is executed.

From "no code" to "all the code" in one easy click.
/pethate on
It might be the local standard, but perhaps you can ask "what is the point of the comment block which says "DATA DIVISON"", and all the others for that matter.
I didn't think it would take long to find one...
| Code: |
*--------------------------------------------------------*
* A100-LOAD-ITABLE *
*--------------------------------------------------------*
A200-LOAD-CURSOR SECTION. |
Doubly pointless.
Also, what about some meaningful datanames? What is I used for? If you gave it a proper name I (sic) wouldn't have to ask.
And literals? Does 14 have any meaning? It is a limit of something. Say someone has the task to "change the limit of <whatever> to 20" a few months down the track. You've not made their job any easier, have you? And it might be you doing it.
Why are things like I and CTR display numeric? You like the compiler generating a heap of stuff each time you use them?
/pethate off
What are all those CONTINUE's about (just out of interest)? |

Your COMMAREA consists of 4 fields: WS-SRTFIELD -- which is not referenced in your posted code, WS-SRTTYPE -- which is not referenced in your posted code, WS-CNT -- which is set to the value of WS-ITM in your posted code, and a filler of 287 bytes which is never initialized in your code.
If you are thinking the variables in the copybook GWDISPL are part of the COMMAREA, they are not. There is a different 01 level for them.
So based upon what you've posted, the ONLY COMMAREA variable you can use is WS-CNT becsue none of the other data in COMMAREA is ever initialized by your posted code. Have you checked WS-CNT to make sure it has a value when you return to the program? |

I can't speak for the TS, but I sometimes throw in some extra CONTINUEs to provide convenient places to set breakpoints. IBM's Debug tool doesn't allow you to set breakpoints at END-IF statements, so sometimes I throw in a CONTINUE immediately after the END-IF and set the breakpoint there. This is especially useful (to me) when the END-IF is at the end of a paragraph. I (usually) delete the extraneous CONTINUEs when I am done. |

Your counter is in the W-S.
When you do RETURN TRANSID COMMAREA, that piece of storage is saved somewhere by CICS.
When the program is restarted, the same piece of storage is returned to you in the DFHCOMMAREA in the LINKAGE SECTION.
In the W-S you have nothing!
Add in B200-RCV-PARA:
| Code: |
| MOVE DFHCOMMAREA TO WS-COMAREA |

Thanks Don.
I find it funny, but that is me. I guess CONTINUE appears in the XREF, END-IF not. Just for fun, you can even use EXIT (I'm sure it used to be "must be in a paragraph on its own"). A casually-encountered EXIT is treated as a CONINUE. IE, neither generate any specific code, they don't "do" anything, but can be targets for generated branches, or generate branches themselves, and the EXIT in its proper place can get loads of stuff generated, fo course. |

Hi All,
Thank you all for the valuable inputs provided. Now I am able to retain the value of WS variable in my program after executing RETURN TRANSID COMMAREA also.
Marso,
I have changed the code as you sugeested and my program is working fine.
I have added the below code to the code pasted above.
| Code: |
LINKAGE SECTION.
01 DFHCOMMAREA.
05 LK-SRTFIELD PIC X(15).
05 LK-SRTTYP PIC X(1).
05 LK-CNT PIC 9(3).
05 FILLER PIC X(287). |
Below code in B200-RCV-PARA after Receive Map statement.
| Code: |
| MOVE DFHCOMMAREA TO WS-COMAREA |
The above mentioned COMMAREA declaration is similar to WS-COMMAREA.
Thanks
