However, in the conventional graph scientific calculators and the like, when describing a graph display program, a user inputs predetermined commands one by one in order and describes them. The operation of inputting various graph display commands having different types and numbers of arguments depending on the type of graph to be displayed has been very inefficient. Further, since the operation of creating the graph display program and the graph display processing were completely separated, it was not possible to correct the graph display command while checking the display state of the graph or to newly input the command. Therefore, for example, when inputting a command for enlarging a part of the displayed graph, the input operation of the graph display program and the graph display process are repeatedly switched, and the correction is repeated to obtain the optimum value. It was a trial-and-error task, such as searching, which was very complicated.

Next, the CPU 2 accepts a parameter value input by the user via the input unit 3 to the window command setting screen 4q and performs a parameter value input process (step S204). Furthermore, CPU2
Determines whether the user has pressed the [EXE] key of the input unit 3 (step S205), and when it is determined that no input has been made (step S20).
5; NO), the process returns to step S204, and the data input process is continued.

If it is determined that the [EXE] key has been pressed (step S205; YES), a Window command based on the parameter value input in the parameter value input process of step S204 is used to generate a graph display program. The window command is inserted at the position of the cursor 4c on the screen 4m (step S2).
06; see FIG. 8 (b)). Then, the CPU 2 determines whether or not the current display state is the graph display program creating screen 4m (step S207). If it is determined that the current display state is the screen 4m (step S207; YES), the cursor 2c After displaying the program with the window command inserted at the position (step S20)
8) Then, the process returns to step S201 to continue monitoring the key input. If it is determined that the current display state is not the graph display program creation screen 4m (step S207; NO), it is determined that the current display state is the graph display screen 4n, and the process proceeds to step S211 described later. I do.

If it is determined in step S202 that the key input is not made by the [Window] key (step S202; NO), the CPU 2 subsequently proceeds to the key input made by the [G ← → T] key. Is determined (step S209), and if not (step S209; NO), other processing other than switching between the graph display (G) and the text display (T) is performed (step S209). Step S213).

When it is determined that the operation is performed by the [G ← → T] key (step S209; YES),
Next, the CPU 2 determines whether or not the current display state is the screen 4m for creating a graph display program (step S210). If it is determined that the current display state is the screen 4m (step S210; YES), the graph display is performed. The program content from the top of the program input to the program creation screen 4m to the position of the cursor 4c is executed (step S211), and a graph is displayed on the graph display screen 4n based on the content of the program (step S211). Step S2
12) Then, the process returns to step S201 to continue monitoring the key input.

If it is determined in step S210 that the current display state is not the graph display program creation screen 4m (step S210; NO), the display screen is switched to the graph display program creation screen 4m (step S210). (S214) The process returns to step S201 again to continue monitoring key input.
