Hi,
I have a parm-member having a list of dataset names.
The dataset list changes on a daily basis.
I have a cobol program where i'll be reading this parm member and get the dataset name.
My question:
Is there any way where i can check whether the dataset is empty or not in my cobol program? I have only the dataset name which is coming from the parm-member.

I believe an empty dataset status-code on an OPEN will be '35'.

Hi,
What's the definition of Parm-member?
| Code: |
| //DDname DD DSN=XXXXXX.ANUJ.PDS(member), |
READ DDname in COBOL program, if on first READ EOF reached file is empty.. I'm confused a little, probably you are not looking for this..
Please explain a bit more. |

hi,
i am not using the dataset as a DD in a JCL, i have only the dataset name which comes into the program.
Simply saying:
In the program i have the dataset name, how to check whether that dataset is empty or not.
I am not reading any dataset to check if it is empty... |

Hi,
It's a COBOL Forum so the general perception was to use READ verb, if you have some thing other than COBL you need to tell us about that.
This

needs clarification.
And if not this

what are the other options avalable to you ? |

You are clearly saying, You are passing DATASET through PARM parameter so only way is to handle it whether the DATASET is EMPTY or NOT programitically..
I am assuming you passed PDS name through PARM say X.Y.Z(member)
one way is
Route JCL statement with IEBCOMPR utility for comparing input dataset against an EMPTY dataset(external source- EMPTY daatset) by routing statement to INTRDR(internal card reader), then
> Check for RC if it ZERO means the input datset is EMPTY(since you are comparing against EMPTY DS of external source)
> Check if RC is 8 means the input DS is non EMPTY
Refer IEBCOMPR utility for code
Hope you are clear..... :o) |

In "standard" (by standard i mean SELECTs, FDs, etc) cobol, no.
You could investigate dynamic file allocation from within cobol or you could call an assembler routine, but my preference is to redefine the requirement. |
