<p>PURPOSE:To move, erase and display plural windows through only one operation by grouping and controlling plural windows. CONSTITUTION:When an instruction 21-3 to operate grouped windows in a program 21 is found, first a window group recognization routine 22-4 is executed. The instruction to operate the grouped windows needs to specify an identifier in one window among grouped ones, or to specify a group identifier. If the group identifier is specified, the window group recognization routine 22-4 considers said group identifier the table number of a group table 2-2, and erases or moves the window specified by the window identifier stored in the table according to a window control routine 22-5.</p> |
