I have cobol program that link a assembler program
Below the commarea of cobol program
| Code: |
05 COMMREG.
10 COMM-IND PIC X(1).
10 COMM-BRN PIC X(4). |
Below is the cics command to link
| Code: |
EXEC CICS LINK
PROGRAM('REFBRAN')
COMMAREA(COMREG) LENGTH(5)
END-EXEC. |
The assembler source is mentioned above and i am new to assembly language.
Will my program return the data from TCTUA area to the calling cobol program.
correct my program, if i am wrong and thanks in advance. |

Is it just illustration or your real stuff? If it real, REFBRAN will be S0C1 when executed. What you expect by issueing CICS LINK
PROGRAM('REFBRAN') ? |

Several things -
01) Specifically use DFHEIENT (and avoid the default) instead of a CSECT. It's a cleaner approach and the CSECT will be built for you.
02) I don't see R7 being loaded by DFHEICAP (commarea addressability).
03) You don't need the GETMAIN, nor DFHCSADS and DFHTCTTE.
FWIW, this can be done easily in the COBOL CICS program.
| Code: |
03 WS-PATTERN PIC 9(005).
03 WS-TCTUAL-LGTH PIC 9(004) BINARY.
LINKAGE SECTION.
01 LS-TCTUA-REC.
03 FILLER PIC X(063).
03 LS-TCTUA-HWORD PIC 9(004) BINARY.
EXEC CICS ASSIGN TCTUALENG(WS-TCTUAL-LGTH) END-EXEC.
*
EXEC CICS ADDRESS TCTUA(ADDRESS OF LS-TCTUA-REC) END-EXEC.
MOVE LS-TCTUA-HWORD TO WS-PATTERN.
|
I'm assuming that the TCTUA Length is a minimum of 65-bytes. You can verify the length via an ASSIGN TCTUALENG command.
If it's less than 65, then you'll get a S0C4.
The PATTERN only needs to be 5-bytes, because the largest signed-halfword value is +32767 and the largest unsigned value is 65535.
HTH....
