PURPOSE:To easily understand a program by displaying intensively plural execution contents of divided instructions in the form of a smaller number of process steps based on the equivalent relation of variables used by each instruction. CONSTITUTION:When the process contents expressed by an instruction string are displayed in a flow chart, a branch instruction or a transfer instruction as well as an instruction or an instruction string which affects such an instruction are detected out of the instruction strings. Based on these results of detection, the instruction strings are divided into plural shorter strings. These instructions usually express a single arranged form of execution contents. Then the execution contents are integrated into a smaller number of process steps based on the equivalent relation of variables used by each instruction. As a result, the instruction strings can be intensively expressed in a flow chart as a single process step. Thus a program producer, etc., can easily understand a given instruction string.
