ESA/390 Interpretive-Execution Architecture, Foundation for VM/ESA

The interpretive-execution facility of Enterprise Systems Architecture/390TM (ESA/390TM) provides an instruction for the execution of virtual machines. This instruction, called START INTERPRETIVE EXECUTION (SIE), was initially created for virtualizing either System/370m or 370-XA architectures and was used later for virtualizing ESA/370' and ESA/390 architectures. SIE has evolved to provide cap...
