Block size (BLKSIZE)

Use the block size value to specify the maximum length of a block for newly created data sets.

The block size value can be obtained from an SMS data class, inherited from a model data set, or you can enter a value.

If you did not specify an SMS data class or a model data set on the first wizard panel, you are required to enter a value for the block size.

If you did specify an SMS data class or a model data set on the first wizard panel, then the block size will be obtained from the SMS data class or model data set. You can choose to override the obtained value, by selecting "Use this value:" and entering a block size.

If you specified both an SMS data class and a model data set on the first wizard panel, then the block size will be obtained from the model data set. You can choose to override the obtained value, by selecting "Use this value:" and entering a block size.
