Description

Program input system

Priority: October 18, 1978 Japan 128291/78 The invention relates generally refers to a computer program system and in particular to a program input system for entering a program into a computer.

In general, programming is a process through which a sentence generated by instructions for a computer to perform desired operations. The main steps that must be taken before a program completes are the following: (i) understanding the problem and planning the solution, (ii) the preparation of a system flow diagram and a program flow diagram, (iii) the translation of the logical steps described in the flowchart into commands for the calculator.

Referring to item (iii) above, there are instructions either in the machine code, i.e. the basic code of the commands understood by the computer or in some form of a higher level language such as ALGOL, COBOL, FORTRAN and PL / 1. Errors in the coded program are often due to incorrect Use of programming language, incorrect logic in solving the problem and an operator pressing a wrong key. It's tough, to completely exclude these errors. It is therefore important to generate this To reduce errors in the coded program as much as possible.

A known system for entering a program into a computer contains a keyboard and a display unit. If the system has a program is entered into the computer, commands and comments are sent to the display unit where the displayed content is confirmed by a programmer. Thereafter will the displayed content from the display unit to the computer transfer.

In the above-mentioned known system, however, there are many bugs and input errors generated and it is difficult to recover these errors and input errors because the commands and the remarks are arranged in lines and the The number of characters to be entered is very large.

The object of the invention is to provide a system for entering a Program in a calculator that makes it easy to fix program errors find ~ and with which only a small possibility of generating input errors is available.

This task is solved by the characteristics of the identifier of the Claim 1. Further developments of the invention are specified in the subclaims.

Using this system can lead to a large number of errors do not occur because the sequence of function buttons is monitored by the computer. In addition, a programmer or operator can easily find bugs as well the program is displayed graphically and the number of characters is relatively small.

The invention is described by way of example with reference to the drawing, 1 is a perspective view of one embodiment of the program entry system of the invention, FIG. 2 is a plan view of the program input unit 1 of FIG the push button arrangement, Fig. 3 is a block diagram of the keyboard 11 of Fig. 1, FIGS. 4a to 4e show representations used in the program input system of FIG Casket, Fig. 5 is a flow chart for explaining the operation of the Program input unit 1 of FIG. 1 in the case in which the representation of the box SEQ of Fig. 4a is displayed, Fig. 6 is a flow chart for explaining the operation of the program input unit of Fig. 1 in the case in which the box IF of Fig. 4b or 4c is displayed, FIG. 7 is a flow chart for explaining the operation of FIG Program input unit 1 of FIG. 1 in the case in which the box DO of FIG. 4d is displayed, Fig. 8 is a flow chart for explaining the operation of the program input unit 1 of FIG. 1 in the case in which the CASE box of FIG. 4 is displayed, FIG. 9a to 9e are illustrations for explaining the symbols used in the flowchart of FIG Fig. 10 can be used, Fig. 10 is a flow chart for explaining the operation of the central processing unit 3 of Fig. 1, Fig. 11 is a detailed flow chart of block 116 and FIG. 12 is an illustration of an example of a program which is formed by a series of boxes that appear on the screen 21 of the visual Display unit 2 of FIG. 1 are displayed.

Referring to Fig. 1, the program entry system according to the invention includes a program input unit 1, a visual display unit 2 for displaying characters and graphs showing a program input from the unit 1 is, and a central processing unit 3 (hereinafter referred to as CPU) for Processing the program. The visual display unit 2 can program the program in the Form of a sequence of graphical representations, such as boxes and associated Flow lines to show the transfer of control, processing function symbols, like IF and DO, and others Notes to clarify the program Show. The visual display unit 2 further has a screen 21 of large size Dimensions, which is divided into two areas 22 and 23. The smaller area 22 can accommodate a box, while the larger area 23 can accommodate a series of boxes can accommodate. First, a box and from the program input unit 1 entered data is displayed in the area 22, and after entering all the data with respect to the box of area 22 has been completed, this will be den Boxes associated with data at a desired location in the larger area 23 emotional. Thus, a flow chart formed by a series of boxes appears displayed on the screen 21. As a result, a programmer or operator can easily Correct program errors by looking at screen 21. The CPU 3 checks data which have been transmitted from the program input unit 1 processes the data and translates the program represented by the boxes in the area 23 into a higher-level language or a machine language using a compiler.

2, there are two types of keyboards 11 and 12. the Function keyboard 11 contains nine function push buttons, the functions of which are as follows are.

~ CR "(construction) button to initiate the input operation for a box in area 22, "ERL" (input label) button, which is pressed when an as ~ Incoming label "labeled remark on the left side of the box of the area 22 is required, "UPL" (top label) button, which is pressed when a "Upper label" comment on the upper side of the branch of the Area 22 is required "/ *" - Enopf that is pressed when a comment is required within the box of area 22, ST (instruction) button, which is pressed when a command statement is within the box of the area 22 is required, CO C control exit) button that is pressed when the space the transfer of the control is entered, "EIS" (output label) -KnopS, the is pressed when there is a remark on the right Side of the box representation of area 22 is required, "BOX" button, the is pressed when a name of a box in the area 22 and a place of the Area 23 to which the box of area 22 will be moved is entered "ED" button to complete the transmission of the data from the program input unit 1 to the CPU 3.

The above mentioned nine buttons are each with nine electric Switches SO, S1, ..., S8 connected. On the other hand, the data keyboard 12, which is of the same type as the keyboard of a typical typewriter, for typing of data, such as remarks and command instructions, used only after the appropriate Function button has been pressed. The buttons are at predetermined locations inside and arranged outside of the box mark 13. Therefore the probability becomes the generation of input errors is low.

According to FIG. 3, there are nine switches SO, S1, ... S8 corresponding to the nine Buttons of FIG. 2 each connected to nine flip-flops FFO, FF1, .. FF8. if therefore, for example, the switch SO is turned on, the flip-flop becomes FFO reset so that the potential of the output of the flip-flop FFO becomes high. The output signals generated by the flip-flops FFO, FF1, ..0 FF8 are respectively the inputs QO, Q1, ... Q8 of the godier 15 for generating binary data. In this regard, if the potential at input QO is high and the potentials at inputs Q1 to Q8 are low, the potentials at the outputs DO, D1, D2 and D3 of encoder 15 are low. This means that the binary number is C000 is output from the encoder 15. If in the same way the potential at the Input Q5 is high and the potentials at QO to Q4 and Q6 to Q8 are low, the potentials at the outputs DO and D2 are high and the potentials at the Outputs D1 and D3 low.

This means that the binary number "0101" is output from the encoder 15 will. The output signals generated by the outputs DO, Dl, D2 and D3 of the encoder 15 are supplied to the CPU 3 via a device controller 31 when one of the switches SO, S1, .. 88 is switched on.

If one of the switches SO, S1, .. S8 is switched on, will be at the same time a signal S is transmitted from a flip-flop FF9 to the controller 31. The ones from the Output signals generated at outputs DO, D1, D2 and D3 of the encoder 15 are not received by the device control 31 if none of the switches SO, S1, ... S8 is switched on is.

After the device controller 31 has received the signals from the encoder 15 associated with the signal S, the potential of which is high, transmits the Controller 31 sends a control signal to CPU 3. Next, the through the data keyboard (Typewriter) 12 inputted to the CPU 3 via an apparatus controller 32 transfer. The CPU 3 then performs a predetermined operation based on the data that have been transferred from the data keyboard 12. Then the CPU generates 3, a reset signal "R" to reset all flip-flops FFO, FF1, ... FF8.

Every time one of the switches SO, S1, ... S8 is switched on, the above-mentioned operation is repeated.

The box in Fig. 4a labeled SEQ CFsequence) box " has an input flow line and one Output flow line. That SEQ box is used to represent an instruction without a branch instruction.

Each of the boxes in Figures 4b and 4c labeled "IF Box" has an input flow line and two output flow lines. According to Fig. 4b a determination is made whether a conditional statement within the box is sufficient is or not. If so, the control flow travels along the lower output flow line if not, the flow continues along the upper exit flow line. In contrast, as shown in Fig. 4c, when a determination is made, that goes the conditional statement inside the box is sufficient, the flow along the the upper exit flow line, while in the negative the flow along the lower one Exit flowline continues.

The box shown in Figure 4d labeled "DO Box" has two input flow lines and two output flow lines. This DO box is used in the case where a command statement is to be executed two or more times is, where the number is determined as a connection value. The upper exit flow line is therefore connected to another box, its output flow line again is connected to one of the two input flow lines of the DO branch. If the Number of operations performed reaches the connection value, the flow goes along the lower output flow line.

The box shown in Figure 4e, labeled the ~ CASE box " has an input flow line and two or more output flow lines. The CASE box is used to represent an instruction with one or more branch instructions used.
