4K pubsets

4K pubsets consist of disks with a 4-Kbyte block structure. The block size of the file must be a multiple of 4K, i.e. BUFFER-LENGTH=*STD(SIZE=n), where n is an even number. In addition, the block structure must not be BLOCK-CONTROL-INFO=*PAMKEY.

In the case of output files, the default value for the BUFFER-LENGTH is dependent on the pubset on which the file is created:

• 2K-formatted pubsets: BUFFER-LENGTH=*STD(SIZE=1);

• 4K-formatted pubsets: BUFFER-LENGTH=*STD(SIZE=2).
