Using ZERO BLKSIZE in JCL.

Hi,
I was thinking that if I male BLKSIZE ZERO in JCL for perticular dataset, it will loose any data on output file. But it did not do so. Why this happens?

Why would it happen? If you don't want the output, use DUMMY or DSN=NULLFILE.
BLKSIZE of zero tells the system to use the "system determined" blocksize for that dataset.

Did you look up BLKSIZE in the JCL reference manual?

BLKSIZE=0 means that developer does not want to specify the BLKSIZE and it will be defaulted to system determined

Did you read that somewhere? Please read the JCL manual.

I suggest that you, too, read the manual.
