XTIOT, uncaptured UCBs and DSAB above 16 megabytes

A program that invokes DFSORT, ICETOOL or ICEGENER can dynamically allocate input, output and work data sets using the options for XTIOT, uncaptured UCBs, and DSAB above 16 megabyte virtual. These data sets are supported to the extent that z/OS supports them.

Note: A program that invokes DFSORT, ICETOOL or ICEGENER should not allocate other data sets such as message, control, list, count, or symbol data sets using the options for XTIOT, uncaptured UCBs, and DSAB above 16 megabyte virtual. These data set options are not supported and the data set will not be recognized.
