1523	 SHARER a Time Sharing System for the CDC	 A time sharing system embedded within the standard batch processing system for the CDC is described. The system is general purpose and file-based providing facilities for file input manipulation editing compilation and conversational execution. It uses a simple scheme for system extension for a machine with only one relocation and memory bound register. No attempt was made to use reentrant code or to simulate segmentation or paging. Implementation time was approximately six man-years with the majority of the code being written in FORTRAN.
