Abstract

An information processing apparatus having a work suspend/resume function which allows operator to use a main memory shared by different processings even when work suspension information is saved therein. A system for allowing a same operational environment as that set up in one information processing apparatus to be easily implemented in another information processing apparatus. A main memory used by a CPU for execution of processings has a function for storing information concerning the state of the information processing apparatus prevailing at a time point when execution of a given processing is suspended by a CPU for allowing the suspended processing to be performed in continuation later on. When the suspension state information has already been stored in the main memory by a former user, the suspension state information is transferred to a removable nonvolatile storage device so that the CPU can perform other processing than the suspended one by using the main memory. The transfer of the suspension state information is performed by the CPU.
