  • the branch element may be added by pressing the upper key. That is, one-way operation in the direction intersecting the line L may be performed.
  • the user when adding an iterative element, as shown in FIG. 22, the user first selects a control element corresponding to the process to be repeatedly executed by using the cross key 80 and the selection key 90. For example, if it is desired to repeatedly execute the process corresponding to the control element 72, move the cursor 70 from the control element 71 to the control element 72 with the right key of the cross key 80, and further press the enter key of the selection key 90. And select the control element 72.
  • a repeating element using the cross key 80 For example, the up and down keys of the cross key 80 are pressed in order. As a result, as shown in FIG. 22, a repeating element 74 and a repeating element 75 are added on the line L as new control elements. The repeating element 74 and the repeating element 75 are added in front of and behind the control element 72 so as to sandwich the control element 72 indicating the process to be repeated.
  • FIG. 22 shows an example in which the up key and the down key are pressed in this order
  • the repeating element may be added by pressing the down key and the up key in this order. That is, bidirectional operation in the direction intersecting the line L may be performed.
  • the information processing apparatus 60 can also add a control structure classified into branching and repetition to the program by an intuitive and simple operation.
