Common Operating Memory Area Overview
The area allocated as the Common Operating Memory Area is contained in
the CPU Bus Unit Area within the CPU Unit's CIO Area. The beginning word
of the Common Operating Memory Area is determined by the unit number set
for the PCU using the following equation.
Beginning word of Common Operating Memory Area: n = CIO 1500 + (unit
