DEFINING AND ALLOCATINGSPACE FOR VSAM FILES You can use CMS AMSERV to allocate additional data spaces for VSAM. To
use the DEFINESPACE control statement, you must have defined either the
master catalog or a user catalog which will control the space, and you
must have the volume or volumes on which the space is to be allocatedmounted and accessed.
For example, suppose you have anOS 3330 disk attached to your
virtual machine at virtual address 255. After accessing the disk and
determining the free space on it, you could create a file namedSPACE AMSERV: DEFINE SPACE -
