<p>PURPOSE:To prevent the selection of a question from being unbalanced and to improve operator's advancement by selecting a succeeding specific character string at random at the time of ending input operation. CONSTITUTION:When key operation shown in a figure is executed in steps 5 to 7, display and stored contents are changed. When a '.' (period) key is depressed in a step 8, a new 'proverb' is selected and its leading address is stored in a load pointer. For instance, address data '42BC' (hexadecimal display) are stored. Then the leading thirteen characters of 'proverb' to be a new exercise sentence are loaded to a display memory DM. When the key operation of 'Rome was' is executed by a step 9, display contents and storage contents are changed as shown in the figure.</p> |
