摘要

A predetermined predefined figure element (C2) is designated, and its figure definition statement is modified to obtain a figure element (C2'). If this modification produces an error in the figure definition statement of another figure element (S1), the figure definition statement (M) containing the error is displayed on the display screen (106) to correct it. Then, the figure element (S1) specified by the figure definition statement containing the error and a figure element (C3) defined by using the figure element (S1) are drawn in different colours to correct the figure definition statement which includes the error.
