z/OS MVS JCL Reference

//         VOLUME=SER=25143,SPACE=(CYL,(10000,,100),,CONTIG),
//         EATTR=OPT

The DD statement defines a new partitioned data set. The system allocates 10000 cylinders to the data set, of which one hundred 256-byte records are for a directory. When the CONTIG subparameter is coded, the system allocates 10 contiguous cylinders on the volume. EATTR=OPT indicates that the data set might be created with extended attributes. With this option, the data set can reside in the extended address space (EAS) of the volume.
