Hi Everyone
Need help in creating Assembler copybook equivalent of Cobol in which there is a occurs with in Occurs.
Here is an example of cobol copyboook
| Code: |
01 A_array
15 A occurs 6 times
20 B PIC S9(07) COMP-3
20 C PIC S9(07) COMP-3
20 D PIC X(03)
20 E occurs 12 times
25 F pic X(12)
20 G PIC X(03) |
I coded like below in assembler
| Code: |
A _ARRAY DSECT
A DS 6CL158
ORG A
B DS PL4
C DS PL4
D DS CL3
E DS 12CL12
ORG E
EA DS CL6
EB DS CL6
DS 11CL12
F DS CL3
AL DS (*-A) ==> Length of one array
DS 5CL158==> 5 remaining entries
AN DS ((*-A)/L'A)==> NUMBER OF ARRAY ENTRIES |
Could you please correct me if I am wrong. Thanks much for your help in advance!
Code'd |

If something is wrong, paste your output and any diagnostic messages.
This doesn't look good: AL DS (*-A) |

Thanks Bill for your reply,
We have some Compaction and expansion for the ASM layout. while compiling those modules I am getting below Error. SO I am not sure if there is an issue with Module or my layout change. Could you please help me in this. Thanks.
61310+*,ERROR: OP = 5CL158, OPL = 011CL12
** ASMA254I *** MNOTE *** 61311+ 8,ERROR: UNLABELED DS DOES PROPERLY END ARRAY
Thank You
Ravi |

Please paste the full DSECT from the Assembler output listing, including any embedded messages, and any later messages on the listing.
Please also use the Code Tags to preserve spacing.
Look at the line I mentioned. If you want to Define Storage, you will need to do more. Do you instead just want to EQUate a value? And for the next one two lines later? |

Hi Bill, Thanks much for your response, I am not sure If I can post assembler source here.. Sorry for that..SO I have tried changing like below code and it worked.
| Code: |
A DS 6CL158
ORG A
B DS PL4
C DS PL4
D DS CL3
E DS 0CL144
ORG E
EA DS CL6
EB DS CL6
DS CL132
F DS CL3
AL DS (*-A) ==> Length of one array
DS 5CL158==> 5 remaining entries
AN DS ((*-A)/L'A)==> NUMBER OF ARRAY ENTRIES |

Most assuredly, that code did not work. There are two Assembler errors in the code, and 1 completely unnecessary statement. |

Please show the documentation which would allow you to use a DS without a type.
You have an unnamed DS which is within the storage of the field referenced by the ORG. How are you aiming to use that?
How do you want to use the AL and AN symbols? |

IMNSHO  the proper way is ...
| Code: |

if You change something in the inner dsects the final ds will be automatically adjusted
and You will need TWO register to navigate the inner ARRAYS/OCCURS
or even better
| Code: |
****** ***************************** Top of Data ******************************
- - - - - - - - - - - - - - - - - - - 10 Line(s) not Displayed
000009 ECOUNT EQU 12

000014 ACOUNT EQU 6
000015 DSECTA DSECT
000016 B DS PL4
000017 C DS PL4
000018 D DS CL3
000019 E DS (ECOUNT)CL(SIZEOFE)
000020 G DS CL3

000023 S DS (ACOUNT)CL(SIZEOFA)
000024 SIZEOFS EQU (*-S)
000025 END
****** **************************** Bottom of Data ****************************

to get the same result

sorry I had a finger check ...
in both examples add something like
| Code: |
...
...
...
000023 MAIN CSECT
000024 S DS (ACOUNT)CL(SIZEOFA)
000025 SIZEOFS EQU (*-S)
...
...
...
|
to get
| Code: |
...
...
...
000077 000000 00000 003B4 15 MAIN CSECT
000078 000000 16 S DS (ACOUNT)CL(SIZEO
000079 003B4 17 SIZEOFS EQU (*-S)
...
...
...
|
S the main <container> should be in a csect to reserve space |

Hi Bill,
Sorry to confuse you with sample code, Below Is the ACTUAL code Which I used
| Code: |
MQWERT_ARRAY DSECT
MQWERT DS 6CL188
ORG MQWERT
MQCTUVLU DS PL4
MQCTUFVL DS PL4
MQCTUPRD DS CL3
MQCTUTYP DS PL1
MQCTUQTY DS PL4
MQCTUSES DS PL4
MQCTUSEA DS 0CL144
MQCTUYR DS CL4
MQCTUMNT DS CL2
MQCTUDAY DS CL2
MQCTUHR DS CL2
MQCTUMIN DS CL2
MQCTPKS DS CL132
*
MQCTUSTR DS CL12 TYPE OF LAST EFFORT SENT
MQCTUEND DS CL12 TYPE OF LAST EFFORT SENT
MQCTUAL EQU (*-MQWERT) LENGTH OF ONE ENTRY
DS 5CL188 5 REMAINING ENTRIES
MQCTUAN EQU ((*-MQWERT)/L'MQWERT) NUMBER OF ARRAY ENTRIES |
Code'd again |

10 MQCTUFVL COMP-3 PIC 9(7).
10 MQCTUPRD PIC XXX.
10 MQCTUTYP COMP-3 PIC 9.
10 MQCTUQTY COMP-3 PIC 9(7).
10 MQCTUSES COMP-3 PIC 9(7).
10 MQCTUSEA.
15 MQCTUYR PIC X(4).
15 MQCTUMNT PIC XX.
15 MQCTUDAY PIC XX.
15 MQCTUHR PIC XX.
15 MQCTUMIN PIC XX.
15 MQCTPKS PIC X(132).
10 MQCTUSTR PIC X(12).
10 MQCTUEND PIC X(12). |
Is that approximately (excluding decimal places) how you expect your COBOL record-layout to look? |

One little tidbit to watch out for in the future (so you don't get burned) are Assembler aligned fields, such as halfwords (H), fullwords (F) and doublewords (D). Their counterparts in COBOL must be suffixed with SYNC.
