In a program display apparatus, a block portion, an iteration control portion and a data description portion designated by a quote construction are extracted from an inputted program expressed by characters. A relationship of inclusion between these portions and a hierarchical relationship are extracted. Each of these portions is replaced by a figure having, for instance, a rectangular shape, and thereafter displayed on a display screen. When one block portion is included into another block portion, the rectangular figure corresponding to the one block portion is included within the rectangular figure corresponding to another block portion on the display screen. Then, both the inclusive relationship or hierarchical relationship between any two block portions, the iteration control portion and a data description portion designated by a quote instruction of the program may be visualized.

Program display method and device, and also program generation method

The present invention relates to a method of displaying an execution status and an execution history of a program for a computer system, associated with a source program and a module relation diagram. The method of displaying program execution according to the present invention displays the processing results of each of execution units, execution statuses of an iteration, a conditional branch, a recursive call and so on super-imposed on the source program displayed on a screen in the vicinity of the respective execution units. Information on execution status is also displayed corresponding to the module relation diagram. Further, a program execution history is preserved so as to allow a reproduced display thereof in the above-mentioned form by request.

Method of displaying program execution for a computer

A tablet comprising conversion means to convert component forces at three fulcra of an external force applied to one point on a faceplate into electric signals, sensing means to sense that no external force is applied, memory means to store the output signals of the conversion means at the respective fulcra as offset values at, at least, one point of time in the period in which no external force is applied, control means to control so as to execute writing into the memory means upon receiving an output of the sensing means, subtraction means to subtract outputs of the memory means from the outputs of the conversion means at the respective fulcra, and calculation means to execute calculations for evaluating coordinates of the point to which the external force has been applied, from outputs of the subtraction means in accordance with the output of the sensing means.
