Based on the relationships defined, the related objects can be either a single generation if a GDS is specified or multiple generations if a GDG base is specified. Object names display in the same format used to create the relationship. For relative GDSs, the extract file contains their relative as well as their absolute file names.

When using relative generation, the data set associated with the generation specified must exist or the object will be excluded from the extract, as is standard behavior for all missing objects.

When a GDS is extracted, each generation is treated as a separate object and will have a different object number. At load time, each generation can be loaded to a different data set.

When a GDG base is extracted, all generations are processed together and will be assigned a single object number. At load time all the generations are part of the same object.

Important

File-AID/RDX does not support extracting from and loading to tape data sets.
