Abstract
In an electronic computer system wherein, when a microprogram-controlled central processing unit receives a stop signal from a console, the contents of a group of registers are assigned to predetermined fixed areas in a main memory and, in response to a start signal, the assigned contents of the group of registers are delivered from the fixed areas to the group of registers. The reading and writing of the contents of the group of registers within the central processing unit is effected for the fixed areas of the main memory in which the contents are assigned.
