Hi friends,
I have a query regarding the BLKSIZE parameter. Any limit is there for specifying this parameter. i,e the size should not be greater than a number.THis was asked by my interviewer.

Thanks and regards

Simham,

The number of bytes that you specify for BLKSIZE depends on the device type and the record format for the data set. The maximum is 32760 for DASD data sets and 2,147,483,648 for tape or DUMMY data sets, except for data sets on magnetic tape with ISO/ANSI version 3 labels, where the minimum value for BLKSIZE is 18 bytes and the maximum is 2048 bytes.

Hope this helps...

Cheers

Kolusu
