Other types of objects

Among other objects, processes had a very complex and not very interesting structure, while most other kinds of objects were fairly straightforward. One item of interest was the representation of subprocess maps. These were maintained in two forms, logical and compiled. The logical form specified, for each entry, a file (through MOT-index-unique-name pointer), file address, logical memory address, count and read only flag. The compiled version converted these entries to absolute ECS and CM addresses. Associated with the compiled version was a compaction count. Thus, the compiled version constituted a secondary form of absolute pointers.
