<p>PURPOSE:To reduce the burden on an operator and to improve the operability by automatically making a window wherein there is an object active and displaying the window when the object in the window other than a window to be operated is accessed. CONSTITUTION:When a command ends normally, 0 is put in the status information part of the active window A1 in a control table 1. When the command ends abnormally, non-0 data is put in the status information part and in this case, a window switching controller 01 tries to execute the command stored in a command buffer 2 for a non-active window under its control and stores the result in the status information part of the window in the control table 1. If the status information part of a window B1 becomes 0, the window B2 is made active and the execution result of the command is displayed in the window B2.</p> |
