Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to a program computer suitable for office processing, and particularly to a computer that can program a combination of character strings and numerical data as comments.

An object of the present invention is to provide a program computer that can output comment information arbitrarily entered by an operator in place of program storage instructions.

Conventional program computers can output comments programmed in BASIC language or the like, but it is generally impossible to change program comments once written. That is, for example, a comment programmed as PRIN "MODEL" B will always appear in M along with the numerical data of B.
It was output as ODEL.

In this case, character variables have been defined to change comments. However, this method has the disadvantage of being extremely complex, i.e., even if character variables are used, the print statement only executes printing, and in order to change the comment fc, it is necessary to create a program that adds an input statement, etc. This has the drawback of inevitably complicating the program.

The present invention was made in view of the various shortcomings of conventional program calculators, and it is simpler and easier to create programs than methods that output (print, etc.) a combination of character variables and numerical data. It is an object of the present invention to provide a program computer that can appropriately replace program storage instructions with key human comment information.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the present invention. In the figure, 1 is a memory (a part of the RAM area) that stores program instructions, and 2 is a block diagram that stores comment information manually inputted by a key in place of the program instructions. This is a comment information input means for inputting, for example, if a programmed comment is
In the case of "DEL", there may be cases where you want to input the model number of a specific model as a comment, and this is for inputting an arbitrary model number. 3 is a circuit that determines whether or not the above comment information has been input. Specifically, this is determined by a key controller circuit, an ALU (arithmetic unit), etc. 4 is an output buffer memory for temporarily storing the program storage command or comment information entered manually in place of this command. 5 is an output device for printing or displaying the contents of the output buffer memory. 6 is an output device for reading program instructions from the program instruction storage memory 1 and inputting them into the output buffer memory 4; ■ A ROM that describes the processing procedure for inputting into the output buffer memory instead of program instructions and a CP that executes a series of processes.
This is one calculation control means including U.

FIG. 2 shows an example of program instructions written to the RAM for each program step. This instruction is written to the program instruction storage memory mentioned above, and in the first step, the character string ``MODEL'' is written as a comment.
” and the / to distinguish between character strings and numerical data, the code (alphabetic/numerical) and the () part to write the numeric value. Similarly, in the second step, as a comment “QUANTITY ” is written,
Subsequently, numerical data corresponding to the comment is written. FIG. 3 shows an example of a program instruction written to the output buffer memory. This program command is configured such that, when the input comment information S exists, it is replaced with comment information, and the comment information is output with priority.

FIG. 4 is a system configuration diagram of a program computer according to the present invention.

In the figure, the system is roughly divided into various controllers (for keys, display, and printing), and a ROM that stores procedures for reading and writing various instructions from memory.

Processing is accomplished by assigning various JOB (display, print, calculation, etc.) units to the ROM.

The above-mentioned program instruction storage section, the output memory, the program step counter, the RAM that stores various data such as flip-flops (or flags) that are set when a comment is input, and the above-mentioned controller and memory. It is broadly divided into CPU, which controls information transfer, calculation, control, processing, etc. The CPU has a working register R, which is used as an RU accumulator, an addressing register, etc. Also, an instruction register IR, a decoder ID for decoding the contents of the instruction register IR, an index register IX,
IY, program counter PC, refresh counter RC, and arithmetic circuit A'LUk are provided, and data is exchanged and addresses are specified using these (RFI data bus and address bus). indicates an interrupt control section.

FIG. 5 is a flowchart for explaining the system operation of the present invention.

First, write a comment (“MO
When a program containing DEL'" is written and execution is started, the first step of the program shown in FIG. 2 is executed according to the flowchart shown. At step r++ R
A part of AM) is set to the initial value, and flip-flop A (in RAM), which is set when comment information is input in 1]2, is reset (n2). , then 03
The instruction indicated by the program step counter is executed, and the program instruction in the RAM is stored in the output sofa memory (part of the same RAM area).
(see figure). Next, in n4, the JOB' corresponding to the content that the above command decoded from any of the various JOBs such as display, printing, and calculation.
i Execute (n5). In the case of the example, MODEL?
() is displayed and the key is waiting for human power (n6). In step n6, for example, the program command rMODEL
? If you want to prioritize and output the comment information entered manually instead of ()J, consider inputting TV351 Yami 98200, then proceed to step n7+ns by inputting TV351, and input the comment information at n8. If it is comment information, the process proceeds from step n8 to step n9, and flip-flop A is input.
Determine whether A=1, clear the contents of the output buffer L(n+o) since A is 1, and write the newly input comment information character string (character) k
Store it in the output buffer (n). At step n12, the RAM is stored to indicate that comment information has been input.
Set the inner Philip flop Ai and step n again
Returns to 5, displays TV351, and waits for key personnel at n6. Next, numerical data 98200 is input, n7
Proceed to +ng, and at n8, [judge that it is not a comment input by operating the N key, in this case, proceed to n18,
Write numerical data to the output buffer and write n again
5 displays numerical data along with comments. At this point, when inputting comments and numerical data is completed, step n7
When the program start key (inside the key unit) is operated, TV351 98200 is printed (n14).
Then, the program counter is counted up (n, . . .), and the execution of the second step is started. The second step is QUA
NTITY() is displayed and the key is waiting for human power, but QU
Comment ANTITY (pre-programmed)
If there is no need to change the QU
ANTITY50 will be printed. In this way, a buffer memory for displaying and outputting a group of program instructions corresponding to the program counter (PC in the CPU) (see Figure 3)
take it into.

A decoder (interpreter) separates the images into each job, displays, prints, and performs calculations, or in the case of display, it waits for input. At this time, comments and numerical data input or reception is added, and if the input is a comment, MODEL
? Comments entered after clearing ', for example, TV
By writing the input comment information to the output buffer in step 351, it is possible to print out the input comment information first.

That is, when a key input is accepted, if it is not the start key, first determine whether it is a comment or not, and if it is a comment, if flip-flop A is 0, the output buffer is cleared and the newly input comment is output. You can write on the hippopotamus sofa. Then, it is displayed, Ke37 waits for human power, and if it is a numerical value, it is written in the () section.

By using the output buffer as described above, newly input comments can be printed with priority over comments written in the program. The above example explains how to clear comments written in the program in the output buffer and write newly input comments, but it is also possible to write both comments to the output buffer, that is, add them to the program comment. It is possible to memorize key human comments.

For example, this can be achieved by performing a cursor operation on the output buffer, and the relationship between keystrokes and display is as follows.

Key human power Display 1i> MODEL? ->-Nre1)) MODEL? TV 35
1 MODEL TV351" cursor (P) t operation 7 times Q. By advancing the cursor to and operating the TV 351, the programmed comment and the newly input comment can be combined and output. When the start key is pressed, the contents of this output buffer are printed (or displayed) and execution of the next step is started.

- As explained above, according to the program computer of the present invention, output methods such as printing can be performed by combining character variables and numerical data, such as when you want to make the meaning of the input take more concrete according to the required prompt function. It has the advantage that it is extremely easy to create a program.
