Abstract

The invention disclosed relates to a method for passing shared data by reference from one member of a hierarchical co-routine set to another in such manner as to avoid erroneous dereferencing in CPU information handing operations. The method steps comprise: (1) detecting the absence of storage of a data object at a common ancestor; (2) moving the data from a contained process to the earliest common ancestor in a hierarchical co-routine set; (3) maintaining a table of data movements; and (4) searching the table in order to obtain the name of the data that has been moved and re-establishing the reference.
