Abstract

PURPOSE:To correspond to a picture which is dynamically changed, and to execute the error check of data by informing the input data when an input is completed by a means to control the display condition of a keyboard input area. CONSTITUTION:An input area control table 302 calls a display control part 201. When the keyboard input area is displayed, the input is registered to the table 302. In order to complete the input, an inactive method 303 is activated from an action method 204 and an active method 301 is instructed to finish the input. The method 301 refers the table 302 and a message to inform the data, which are inputted to the keyboard input area, to an application program 111. Thus, the method 204 is activated and the input data are checked. When the input data are unfair data, a reactive method 304 is activated. The method 304 instructs the method 301 to receive the input again and the method 301 returns again to input reception processing.

Frame 6024 uses action method 1nput -action 604 for frame 4o24.
This is what was described in . 1nput-action
Step 604 checks whether the data input to the age input component 4014 (received by a variable called age) is between 16 and 65, and branches depending on whether there is an input error or normal input. If the input is normal, the input data is assigned to the "age" slot of the "employee" frame.

A frame 6025 describes an action method 1nput-action 605 for the frame 4025, and a component 401 called employee number input.
It has a function to check that the data input to 5 is a positive 7-digit value. If the input is normal, the input data is substituted into the "employee number" slot of the "employee" frame 600.

Frame 6023 describes action method 5 select-action 603 for frame 4023 . According to the flowchart in FIG. 5, when a component 4013 called gender input is selected with the mouse, a 5select-action 603 is activated.
5select-action 603 assigns the selected character string (received by a variable called setext) to the "gender" slot of the "employee" frame.

In this embodiment, activation method 301. Deactivation method 303. It is assumed that the reactivation method 304 exists in a frame in the UIMS 102 called ``#Window''.

FIG. 7 is a diagram showing the structure of the input area management table 302. Field 701 is a field that stores an input job title. Field 702 is a field that stores information indicating whether each input area is displayed.
