Hi recently I was stuck in the COBOL calls in CICS region and sending data more than 32k.
I discussed this on same forum. I was convinced that we cannot pass data more than 32k in Call..
But it seems i was wrong.. i as able to pass 42853 bytes of data and got the response..
I am converting BASE 64 to Binary and visa versa. using the conversion modules available on net.
following are my calls and codes..
PGM1 - Main program calling Converter modules :-
Working storage :-
| Code: |
006800 01 WS-C-CONSTANTS.
007100 05 WS-C-PGM-BIN-B64 PIC X(08) VALUE
007200 'OAOZB64 '.
007300 05 WS-C-PGM-B64-BIN PIC X(08) VALUE
007400 'OAOZBIN '.
022500 01 WS-DATA-CONV.
001600 05 WS-LNK-BIN-STRING PIC X(32000).
001700 05 WS-LNK-BIN-LENGTH PIC 9(8).
001800 05 WS-LNK-B64-STRING PIC X(59000).
001900 05 WS-LNK-B64-LENGTH PIC 9(8).
001990 01 WS-REQ-WK-DATA PIC X(60000). |
procedure division :-
| Code: |
046700 MOVE WS-REQ-WK-DATA(1:WS-INT-LEN)
046800 TO WS-LNK-BIN-STRING
046900 MOVE WS-SMG3-INT-LEN TO WS-LNK-BIN-LENGTH
047000
047100 CALL WS-C-PGM-BIN-B64 USING DFHEIBLK
047200 WS-DATA-CONV
047600
047700 MOVE WS-LNK-B64-LENGTH TO WS-CDATA-DATA-LENGTH
047800 MOVE WS-LNK-B64-STRING(1:WS-LNK-B64-LENGTH)
047900 TO WS-DATA-AREA.
048000
066700 MOVE SPACES TO WS-LNK-B64-STRING
066800 MOVE ZERO TO WS-LNK-B64-LENGTH
066900 MOVE WS-SUB-XML-LEN TO WS-LNK-B64-LENGTH
067000 MOVE WS-DESC-PAYLD (1:WS-SUB-XML-LEN)
067100 TO WS-LNK-B64-STRING
067200 MOVE SPACES TO WS-LNK-BIN-STRING
067300 MOVE ZERO TO WS-LNK-BIN-LENGTH
067400****
067500 CALL WS-C-PGM-B64-BIN USING DFHEIBLK
067600 WS-DATA-CONV
068000*
068100 MOVE WS-LNK-BIN-LENGTH TO WS-CDATA-DATA-LENGTH
068200 MOVE WS-LNK-BIN-STRING(1:WS-LNK-BIN-LENGTH)
068300 TO WS-DATA-AREA |
I am passing 32000 Binary data to Base 64 converter in WS-LNK-BIN-STRING it gives 42648 bytes in base 64 format in WS-LNK-B64-STRING. My program was able to receive.
When I sent this 42k string back to Base 64 to binary converter, I was expecting error as this string is more than 32k . But to my surprise this worked and I got perfect 32000 sting back in Binary format. Its was the same data message i converted to Base 64.
That means that we can pass more than 32k data in COBOL call.
My calling program is CICS program and the Called modules are cobol modules. all 3 programs have PCT entries present in CICS region.
for conversion I used modules available on Type_Description_Herehttp://www.redversconsulting.com/tools.php
I have just changed the Linkage section of both the modules as per the WS-DATA-CONV.
Can anybody tell how did this happened? I was under impression that we can not pass more than 32k data in call. |

LINK and XCTL has the 32K limit(COMMAREA).(This can be extended by use of Containers in CICS)
COBOL call has no such limit, so whatever results you got are not surprising. |

Keep in mind that CALL's are local to the given CICS region. You cannot CALL program "B" if it is in another region, because each parameter is passed as an ADDRESS (not the actual data), which is in the Calling (Local) region.
HTH....
