Hi,
Continuing to add to the stack of problems I already have...
I have a requirement to dynamically create files for reports. I could do this with an inhouse assembler utility. This utility takes in the dd name and dsn together with other parameters and creates a new file.
I hvw only one SELECT statement, which points to one Env variable FILEIO01. I have not coded any DD statement in the JCL.
So the Code is like this
| Code: |
SELECT DYNA-FILE ASSIGN TO FILEIO01.
.
.
.
.
01 WS-DYN-OPEN-AREA.
05 WS-DYN-FILE-NAME.
10 FILLER PIC X(14)
VALUE "FILEIO01=DSN(".
10 WS-DYN-DSN PIC X(55) VALUE SPACES.
10 FILLER PIC X(06) VALUE "OLD".
10 FILLER PIC X(01) VALUE X'00'.
05 WS-FILE-POINTER POINTER.
05 WS-RC PIC S9(09) COMP VALUE ZERO.
.
.
.
CALL ALLOC-PGM USING WS-FILE-NAME, WS-DDNAME
MOVE SPACES TO WS-DYN-DSN
STRING WS-FILE-NAME DELIMITED BY SPACE
")" DELIMITED BY SIZE INTO WS-DYN-DSN
SET WS60-FILE-POINTER TO ADDRESS OF WS-DYN-FILE-NAME
CALL 'PUTENV' USING BY VALUE WS-FILE-POINTER
RETURNING WS-RC
IF WS-RC = ZERO THEN
OPEN OUTPUT DYNA-FILE
|
It works cool in the first round, where WS-DDNAME
In the second round the value of the DDname changes into FILEIO02, and the WS60-FILE-NAME is also created dynamically, ie a new file name is created using ALLOC-PGM.
But the DD in PUTENV does not change as it is hard coded, but file name changes. But now PUTENV opens the same file, not the new one created!!!
So finally, it over-writes the old file giving me one useless file and several blank files....
Am I doing anything wrong here? |

New2cobol,
If I remember correctly, you want to output X number of records to a file, close assign a new file open and output x records, again, and again until all records have been written. Right?
This is a small program (complete) using PUTENV to four output files using only one SELECT/FD. Results are below.
I don?t know if there is some environmental condition between your allocate program and PUTENV? Or what. But this seems to work for me.

| How do I declare a 133 record length FBA file using PUTENV ?? Or do you have some link explaining the options of putenv,setenv etc? |

Ok, the file name sizes should be X(55) and we can't add DD statement key words to the arguments... My mistake... Now it is running fine...
Sorry!!! |

new2cobol,
Here is the document that I am working off of for the PUTENV variables.
4.2.3.1 Assignment name for environment variable
I tried the RECFM you have in you code and got an error when I tried it. The only options you can specify are the ones in the document above. I almost never us the ?after advancing?, but when I tried it the file was allocated as ?FBA?. Remove all that is not in the doc above, and you know that you cannot have the DDNAME specified in the JCL you are running.
I got a return code of zero even though PUTENV didn?t work. Don?t know why. It did put out some messages in SYSOUT though.
If you still have problems I will post the entire program again that is producing LRECL=133,RECFM=FBA. This works good for me.
Please let me know your progress,
Sometimes the road is long and we seem to only be making small steps, but will never arrive if we quit.

Congratulations and good luck,
