Abstract

PURPOSE:To use a program library written by using the system of an old machine, by providing program data, having more than one kind of an instruction system with flexibility. CONSTITUTION:A key input part 11 has a mode key 14 for specifying whether flexibility in handling input and output data, etc., is given between an old machine and a new machine, a specifying key 15 for a memory number in writing data, a specifying key 16 for a memory number in reading data, etc. The operation signal of the mode key 14 is outputted (a) to a control part 18 through a binary counter 17. Further, the operation signals of other keys are sent to a key discrimination part 19 and outputted to the control part 18 as signals (b) and l. Further, the discrimination part 19 sends register data the address part of the control part 18 through a line (d), and function data through a line l.
