<ul>
<li> <b>absolute</b><br>
Absolute name of any GDGs will be captured during the initial run of a job (for example: <dsn>.G0001V00). This absolute name will be used during reruns of the job. This is the original behaviour.
<li><b>relative</b><br>
Relative generation (for example: +1 or 0) of any GDGs referenced by a job will be maintained during reruns. If a step which creates a new generation of a GDG is skipped during rerun, subsequent relative references to the GDG will be adjusted to compensate. For example, if a step which creates a +1 generation is skipped during rerun, a subsequent step which reads in generation +1 will be adjusted to read in generation 0. Thus preserving the original intent.
