PURPOSE:To increase the executing speed of a macro instruction program by providing a function to deliver the control to a prescribed program produced by a microinstruction stored in the same program from another prescribed program produced by another macro instruction. CONSTITUTION:The titled system is constituted of an interpreter 2 realizing a macro instruction in addition to a macro instruction program 1 including a program B obtained by coding a microinstruction subroutine and a macro instruction A which shifts the control to said subroutine. The instruction A designates a relative address contained in a macro instruction program of the microinstruction subroutine at the inside of an instruction. The interpreter 2 detects macro instruction out of the program 1 for each step to translate them into a microprogram C and calls an instructed microinstruction subroutine B out of those translated microinstruction subroutines. When the routine B is carried out, the routine of the interpreter 2 is reset and the interpreter 2 detects the next macro instruction.
