HI Robert .
I have been trying running the given COBOL and getting below mentioned values in sysout
ALLOC DIAG CODE = 0000J
ALLOC KEY VALUE = 0064L
ALLOC DIAG CODE = 0000J
ALLOC KEY VALUE = 0064L

Also i see when BPXWDYN is getting called it returns -00000623 as return code .

I tried various ways of using BPXWDYN in Rexx and its working fine .

Is it like i need to modify the program in some way to run properly .
I did changed the LRECL ,BLCKSZE for my particular use .

Regards

Please don't tailgate an old topic, but start with a new question. Especially when the topic is a "Sticky".

Have you looked up what the various codes mean?

Are you not contradicting yourself - either it's working fine OR it's not and you need change - -what is it?

HI Bill ,
Yes i did tried to understand the meaning of codes .
10 WS-BPXWDYN-RC2 > -0643 (ALLOC KEY VALUE )
10 WS-BPXWDYN-RC1 > -0001 (ALLOC DIAG CODE)

I get an idea that there is some key error while calling BPXWDYN.But why is it happening ,i am unable to understand .

Hi Anuj,
I guess the mentioned COBOl program is supposed to have the same effect as below rexx .
ALLOCSTR = "ALLOC DD(G035DD01) DSN('TEST.JXB.PRADEEP.PS')",
"NEW CATALOG REUSE RELEASE",
"RECFM(F,B) UNIT(SYSDA) DSORG(PS) LRECL(80) BLKSIZE(0)"
CALL BPXWDYN(ALLOCSTR)

I meant this RExx is running fine . but COBOL seems to have some problem

Please suggest the meaning of these codes and where exactly i am going wrong .

from Your initial post

it looked like You were trying to run the READPDS cobol example

BPXWDYN has some quirks...
a couple of keywords are different from the <equivalent>ones for allocate

Tried a lot but couldnt fix the problem .

But still thanks a lot to Robert for introducing me to 'BPXWDYN' . I guess its best to use it with REXX.

Just in case anybody has a clue these are the values of the variables i get on calling 'BPXWDYN'
05 WS-BPXWDYN-RC > -00000643
10 WS-BPXWDYN-RC1 > -0001
10 WS-BPXWDYN-RC2 > -0643

You have provided the equivalent REXX code to what you want the COBOL to do, but you have not posted the COBOL allocation statement (use a DISPLAY just before the CALL to BPXWDYN). BPXWDYN does have some quirks, and it is EXTREMELY sensitive to the parameters being passed to it -- but from what I've seen, once you get the exact parameters specified there is no difference between the COBOL and REXX calls to BPXWDYN.

the manual certainly does icon_cool.gif

as per bpxwdyn doc

Understanding Key Errors

The low order two digits is the number of the key that failed the parse, offset by 20. The first key will have the value 21.

The high order two digits is a diagnostic code that indicates where in the code the parse failed. If the high digits are 0, the key itself was probably not recognized. Other values usually indicate a problem with the argument for the failing keyword. Likely causes are blanks in arguments that are not quoted and spelling of key names.

Understanding Dynamic Allocation Error Codes

The return code contains the dynamic allocation error reason code in the high two bytes and the information reason code in the low two bytes.

You can use the high four hex digits to lookup the error code in the dynamic allocation error reason codes table found in the Application Development Guide for Authorized ASM Programs.


nobody will do the manual reading and decoding for You
