PURPOSE:To develop a program in a short time and with high memory availability by putting a page setting instruction into a place right before a branch instruction in the case the number of the page including the branch instruction is not equal to that of the page including the destination of the branch instruction. CONSTITUTION:The branch instruction number (i) of a program 10 is set at a page 1, and the number Pi of the page including a branch instruction is compared with the number Qi of the page including the branch destination address. If no coincidence is obtained between both page numbers, it is checked whether a page setting instruction is already set right before the branch instruction or not. If not, the page setting instruction is set into a place right before the branch instruction and an insertion flag is set. As a result, the page setting instruction is automatically set into the only place necessary for the branch instruction in a program stored in a memory having a page structure via a software development back-up device. In such a constitution, the software development efficiency is improved without deteriorating the memory availability.
