Loading an HDAM or a PHDAM database
In an HDAM or a PHDAM database, the user randomizing module determines where a database record is stored, so the sequence in which root segments are presented to the load program does not matter.
All dependents of a root should follow the root in hierarchical sequence. PROCOPT=L (for load) or PROCOPT=LS (for load segments in ascending sequence) must be specified in the PCB.
