VIOALLOC—control VIO allocation (used with StopX37/II)
The VIOALLOC function changes the allocation of selected temporary data sets to or from virtual I/O (VIO) storage with no JCL modifications.
The z/OS VIO facility provides a significant advantage over normal DASD I/O. VIO resides in the paging space and I/O operations are performed at the speed of page access.
