Overview of delta members

An overview of the existing delta members in a library can be output by means of the operand INFORMATION = DELTA-STRUCTURE in the SHOW-ELEMENT-ATTRIBUTES statement. A complete delta tree will then always be listed, regardless of which member has been specified.

As well as the member designations the internal delta numbers of the members are output to field DELTA# and the internal numbers of the predecessor members are output to field BASE#.

The delta number reflects the chronological order in which the members have been included. Both numbers uniquely describe the chaining of members in a tree; they cannot be controlled by the user. The user can visibly define the chaining of members by proper version specification.
