Using multitasking with tape stacking or cabinet copies
BMC AMI Copy does not terminate stacking on a tape or cabinet copy for a given OUTPUT descriptor at the end of the group or set processing if the OUTPUT descriptor is referenced by a COPY statement for a later group or set. (A set is a set of multitasking GROUP NO COPY statements in the job.) The same tape or cabinet copy is used for all spaces. When BMC AMI Copy detects that a stacked tape or cabinet output is not used in a future group or set, BMC AMI Copy deallocates the device.
