  • Method for bidirectional calling between open system and mainframe system performed by computing device
    Patent number: 10324775
    Abstract: Disclosed is a method for bi-directional calling between an open system module and a mainframe system module, which is performed in a computing device including one or more processors and a main memory storing commands executable in the processors. The method may include: receiving, by a front-end interface, a calling for a mainframe function on the mainframe system module from the open system module program; requesting, by an entrance point processing unit of the front-end interface, information on the mainframe function to a program processing unit of a back-end interface; controlling, by the entrance point processing unit of the front-end interface, a register processing unit of the back-end interface to set a mainframe register value used in the mainframe system module; and transferring, by the front-end interface, a system control to the mainframe system module through a control transfer processing unit of the back-end interface so as to drive the mainframe function on the mainframe system module.
