PURPOSE:To change only the internal realizing method of the abstracted software parts with no change of description of the requested specifications, by storing the actions of a computer into an object against the processing given from outside to the object. CONSTITUTION:When the number of key pushes totalized until the push of a break key is displayed on a screen, '0' is set at a COUNT. A calculation formula 65 serves as a repetitive sentence and both calculation formulas 66 and 67 are repeated until the value of KEY is coincident with the break key. In a system the keyboard parts are retrieved from a word 'keyboard' and a calculation formula 62 is carried out from the words 'pushing KEY'. Then X and KEY are restricted and the name of the pushed key pushed on the keyboard is set at KEY. Thus the value of the COUNT is increased by 1. Then X and COUNT are restricted and the value of the COUNT is displayed on the screen.
