I have a doubt as the question is being asked in a interview, i.e. I have a KSDS file with zero records or NULL records in it. In this case, if i write a COBOL program to open the KSDS file and try to fetch the data from the file, Will it ABEND or will it execute SUCCESSFULLY. And also if i just want to open the file and also try to insert some record in it what would happen ?
Please help me in this regard.

Thanks
Sandeep

Hi,


The program will not abend if you are only trying to acces the vsam file.
but it will a vsam file status of 35 for vsam file bieng empty and hence 47 for unsuccessful opening.

I just tried this by only 1 file in my program which is a vsam file and tried to read it.( also displayed vsam file status i have kept the vsam file as empty).

The jcl ran successfully but displayed vsam file status as 35 for open and 47 after reading it.

****************
STATUS:35
STATUS:47
****************

Bye,
