Abstract

PURPOSE: To enable the execution of special processing stated in an assembler language, by adding a macro instruction as one sequence element.
CONSTITUTION: It is checked whether or not each sequence element picked out from a sequence memory is a macro instruction. If the sequence element is not the macro instruction, calculations are effected according to the sequence contents stored in the sequence memory and the result of the calculations is stored into an I/O memory and picked out. If the sequence element is the macro instruction, jump is effected to the address succeeding to that where the macto instruction is stored. An instruction stated in the assembler language previously stored at the former address is executed.
