2. Description of the Related Art Recently, a full-screen terminal of a type in which all display positions of messages on a screen are address-managed has been widely used. Conventionally, when a TSS is used using such a full-screen terminal, there are the following problems when displaying a general (line-based) message.

FIG. 7 is an explanatory diagram of the prior art.
7A illustrates an example of a message display screen when the screen is full, and FIG. 7B illustrates an example of a message display screen when the execution key is input once when the screen is full.

In the TSS, when a message is displayed from the last line to the first line of the terminal, three stars (***) are displayed on the last line, for example, as shown in FIG. , It is controlled to wait for some input. This state is called a screen full state.

When a key, such as an execution key or a PF key, which causes an input / output interrupt to the host processor is input in a full screen state, the screen is erased and, for example, as shown in FIG. Is controlled to be displayed from one line.

Therefore, for example, when there is a display request to output 10 consecutive messages, if the display start position of the message is after the last line-9th line, all the messages can be displayed at once. It is no longer possible to delete the first several lines of the displayed message before displaying the next message. Therefore, a situation has arisen in which terminal users are not very convenient to use.

[0007] The inconvenience of use is, for example, TSS or T
When hard-copying a message displayed by an SS application program, it is difficult to copy the message at a time, or the connection before and after the message is interrupted when visually checking the message, making it difficult to confirm. Has become apparent.

[0008]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and displays / deletes a general (line-based) message output from a TSS or a TSS application program when a TSS is used from a full-screen terminal. It is an object of the present invention to improve the method and to provide a screen control means which makes it easy to read a message and has good operability.

The scroll key input check processing unit 14 is a processing unit that detects an input of the scroll key registered by the scroll key registration / cancellation processing unit 12.

The line number calculation processing section 15 is a processing means for detecting the line position on the screen where the scroll key is input, and counting the number of lines to be scrolled based on the line position.

The scroll data generation processing section 18 is processing means for generating data for scrolling the screen by the number of lines to be scrolled.

[0013]

The scroll key registration / cancellation processing unit 12 of the TSS input / output control mechanism 11 performs a process of registering, for example, a specific PF / PA key specified by a TSS command as a scroll key and a process of canceling the registration. .

Scroll key input check processing unit 14
Notifies the calculation processing section 15 of the number of lines when the registered scroll key is input. The line number calculation processing unit 15 and the scroll data generation processing unit 18 perform the following control.

In a screen full state or a normal input waiting state,
When the scroll key is pressed, the display content of the current screen is changed to 1
Control to scroll up the line. When the scroll key is input in the full screen state, if there is a continuation of the message, the screen is scrolled up while displaying the next message by one line. Further, when the scroll key is input after moving the cursor to an arbitrary position on the screen, control is performed to scroll up the screen so that the line with the cursor after the movement is at the top.

Accordingly, the terminal user can see the message of the maximum display line minus one line of the terminal at a time, no matter what line the display start position of the message starts.

[0017]

FIG. 2 is a flowchart showing a scroll key input check process according to an embodiment of the present invention. The scroll key input check processing unit 14 shown in FIG.
Are performed.

When a key is input from the terminal, it is determined whether or not the key is a key registered as a scroll key by the scroll key registration / cancellation processing unit 12 in advance. If it is not a scroll key, the following processing is skipped and it is treated as input of general data.

When a registered scroll key is input, it is determined whether the current state is a state in which the scroll key is valid. Since the scroll key uses a general key (PF key or the like) assigned to the keyboard on the terminal side, during operation of the application program 20 which wants to directly access the key, the scroll key is not regarded as the scroll key, and the application program 20 is not considered. Notify as is. For this reason, it is determined whether or not the scroll key is valid depending on the operation state or the specified state of the application program 20, and when it is necessary to invalidate the scroll key, it is treated as input of general data.

When a registered scroll key is input,
When it is in a state where it can be made valid, the line number calculation processing unit 15 shown in FIG. 1 is called to detect the cursor position and calculate the number of lines to be scrolled.

FIG. 3 is a flowchart showing a process for calculating the number of rows according to the embodiment of the present invention. The row number calculation processing unit 15 shown in FIG. 1 performs, for example, the processing shown in FIG. It is determined whether the cursor position indicating the operation target position on the screen is currently the last line of the terminal.

If the cursor position is not the last line of the terminal, it is determined whether or not the cursor position where the scroll key is input has changed from the position (line) where the cursor was previously displayed.

If the cursor position has changed, the number A of lines to be scrolled is set to the line number −1 of the cursor position. If the cursor is on the last line of the terminal, or
If the cursor position has not changed, the number of lines A to be scrolled is set to one.

FIG. 4 shows a flowchart of the scroll data generation processing according to the embodiment of the present invention. The scroll data generation processing section 18 shown in FIG. 1 performs, for example, the processing shown in FIG.

The scroll order is stored in the output buffer by the number of lines A to be scrolled calculated by the line number calculation processing unit 15. The scroll order is a command to the terminal for instructing that the first line of the screen be deleted by one line and the content of the currently displayed screen be scrolled upward by one line at a time.

As the cursor display position, a value obtained by subtracting A from the position where the cursor was last displayed last time is set as the current display position. 5 and 6 are diagrams showing examples of screen control according to the embodiment of the present invention.

Next, a display example on an actual screen will be described with reference to FIGS. In FIG. 5 and FIG. 6, a portion represented in uppercase represents an output message, and a portion represented in lowercase represents input information from a terminal.

FIG. 5A shows an example of a screen when a scroll key is input without moving the cursor. When the scroll key is pressed once in the normal input waiting state as shown in FIG. 4A, the display content is scrolled up by one line as shown in FIG. 4B.

FIG. 5B shows an example of a screen when the cursor is moved and a scroll key is input. As shown in (a) of this figure, in the normal input waiting state, for example, if the cursor position is moved to the third line of ccccc and the scroll key is input, as shown in (b), ccc
The screen is scrolled up so that the line of cc becomes the first line of the screen, and control for returning the cursor to a new input position is performed.

FIG. 6A shows an example of a screen when the scroll key is input without moving the cursor when the screen is full. When the scroll key is input four times in the full screen state as shown in FIG. 11A, the control for scrolling up the displayed content by one line is performed four times, and the output waiting messages "III...", " JJJ ... "is additionally displayed. As a result, the display screen becomes as shown in (b).

FIG. 6B shows an example of the screen when the cursor is moved and the scroll key is input when the screen is full. As shown in (a) of this figure, when the screen is full, for example, if the cursor position is moved to the line of ffffff and the scroll key is pressed, the screen is scrolled up so that the line of ffffff becomes the top line of the screen. Then, the output waiting message "III ...
… ”And“ JJJ …… ”are additionally displayed, and the display screen is
(b).

[0032]

As described above, according to the present invention,
Since the terminal user can bring any message displayed on the screen to the first line of the screen, the terminal user can display the message corresponding to the maximum display line of the desired screen minus one line at a time. become able to. This eliminates the need to copy across the screens even when making a hard copy of the message of the maximum display line minus one continuous line, thereby providing an easy-to-use man-machine interface.
