ABSTRACT:
A data processing system is described wherein, during linkage to a subroutine, by a single machine instruction, a complete status save and the assignment of a dynamic work area are effected. By another single machine instruction the process is reversed. The elements of the complete machine status and the dynamic work area are retained in a hardware controlled stack, thus permitting nesting of the subroutine calls.
