Abstract

PURPOSE:To check matching between the input data and a program without using any special instruction for check and also in case a data input time, by providing a data attribute designating field for input data and a program language input means including an input instruction which indicates the data input. CONSTITUTION:A flag showing the attribute of the data to be fed is set in a system working area of a main memory which undergoes the access control by a CPU. For the program executing procedure, it is decided whether or not a program pointer PP is showing the termination of a program area. If the PP does not show said termination, the data (instructions, sentences) starting at an address position shown by the PP is executed. When an instruction (sentence) is executed, the PP is replaced in accordance with the instruction. This instruction means an input instruction which designates the input of data from an input device, an instruction which designates the four rules of arithmetic, etc. In case, the PP shows the termination of the program area, the processing is carried out for program end and the control is shifted to the 1-row input processing.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a 16-report processing system that executes a program written in a programming language input from an input device such as a keyboard as needed. Regarding.

[Technical background of the invention and its problems] In general, in this building's JM1 installation, an input word 711 that specifies data input from an input device is said in a program created in the Glodarum language. If so, what about the input instruction? 'it' means that a data input operation is performed using the human-powered device, and the corresponding data is taken in as input data. If the data imported in this way does not satisfy the data attributes (for example, numbers) required by the program, there is a risk that the program will be interrupted. Conventionally, therefore, a special instruction for checking the consistency of input data with the program has been included in a program (user program), and the data has been checked using this instruction.

For this reason, conventional information processing apparatuses have the disadvantage that a program that is automatically generated by inputting a program from a human-powered device becomes duplex.

This invention was made in response to the above-mentioned VC.The purpose of this invention is to check the consistency of human data with a program without preparing a special instruction for checking, and moreover, at the time of data input. An object of the present invention is to provide an information processing device that has a data attribute specification field that specifies the nature of the data to be input, and that executes an input command that instructs data input. Program to manually learn programming language 8
Word input is complete. When executing an input command in a programming language input by this input means, a flag corresponding to the content of the data attribute specification field in the command is turned on by a flag-on means, among data attribute flags indicating various data attributes. . Data importing means Q, when data is input from the data inputting means for inputting each building data according to the above input command, the attribute of this Ml f'-evening is 7.
The 1st of this invention, which detects whether or not it matches the data attributes indicated by the flag on the lagon, and imports input data according to the detection result shows one of the inventions in the first invention. 1 shows a configuration of an information processing apparatus such as a personal computer system according to an example. In the figure, 10 (a CPU forming the center of the device) includes an arithmetic/logic device 4 and a control device (not shown).

Next, the operation of one embodiment of the present invention will be explained with reference to the flowcharts shown in FIGS. 3, 5, and 6, and the program shown in FIG. 4. It is now assumed that a system program written in machine language is stored in the system program area (5PAJ21) of the main memory 20, initialization of each part has been completed, and the apparatus shown in FIG. 1 is ready for operation.

In this state, the system program runs.

Figure 3 shows a flowchart of the system program. First, in step A, data input processing from the keyboard (KB) 5 (+) is performed using the carriage return key (
C/R key] is operated (that is, until the end of one line input is instructed).In the next step B, the data input in step A is analyzed.CPU 1 0 When executing steps A and B, it is determined whether the input data is data that specifies execution (called a command) (Stella 7''C). j, l, 3, CPU is

T) Command to print out from 3o (Step I), program area (PA) 2 J VC
Execute the stored program (steps J-M
) command (referred to as RUN command). Therefore, when the input data is a RUN command, the program stored in the program area 23 of the main memory 20 is executed by repeating steps A to D.

Program area (PA) For 2311C: Valued program execution hand + 111'l [As follows. The start address of the program area 23 is set as the program pointer PP (step J).
In short, the program pointer PP is in the program area 23.
A determination is made as to whether or not it indicates the final stage (Stella fK). Step 4 (If the judgment is No, the data (command, statement) starting from the address position indicated by the program pointer PP is executed (Stella fL
). When one life hold (text) is completed, the pointer PP is updated in accordance with the seventh command. These commands include input commands (INPUT commands, INPUT statements) that designate data input from an input device, commands that specify addition, subtraction, multiplication, division, and the like. Note that if the determination in step is YES, program termination processing (step M) is performed, and H7ll ra is transferred to one-line input processing (step A).

Now, it is assumed that the program shown in FIG. 4 is stored in the program area (PA) 2J of the main memory 20 in line number order by repeating steps A to D described above. In Figure 4, rto4. rzo”, r3o”,

After the program shown in FIG.
], when the RUN command is input, the program executes the above-mentioned move 1111! It is executed at t. First, a statement execution process (Stella 7'L) regarding the command (statement) of line number -710 is performed. The command (statement) of line number 10 is fi ERASE command (statement), and when Stella fL is executed, the entire CRT display is erased (blank cleared). At this time, the program pointer PP is updated. Statement execution processing (step L)
When the process is completed, a determination process is performed in step. In this example, where instructions after line number 20 remain, the determination for the step is No. As a result, the command (statement) of the next line number 20, that is, the input command (INPUT
A statement execution process (step L) regarding the command) is performed.

In the statement execution process, as shown in the flowchart of FIG. 5, it is determined whether the Amazumi-Yo-Urine command (sentence) is an INPUT command (C-sentence) (Stella 7'L1).
. If this determination is NO, another sentence execution process (step L15) is performed. Said FJRAsFi
; Commands and the like are rejected in step L15. Note that the specific processing procedure of step L15 is omitted because it is not directly related to the present invention. On the other hand, if the determination in step Ll is YES, the main memo I) 20 system working area ゛(, SWA
) Capital letter flag (LCF) provided in 22
22r and the numeric flag (NF) 222 are turned off (step L2). When Stella 7'L2 is finished, in the INPUT statement, r INPUT J
(which is an identifier that defines the attributes of the input data)
It is determined whether or not r ATTRJ is written (step L3). If this determination is YES, the next character (symbol) "("
4), a process (step L5) is performed to determine whether the next character is 16D''.

The determination at step L5 is YES-1! In the case of lJ constant, that is, in the case of numerical data designation, the numerical flag (NF) 222 is turned on (step L6), and the process advances to step L9. Further, if the determination in step L5 is No, that is, the character to be determined is not "PaD", the character is l-"t,".
A determination is made as to whether this is the case (step L7). If this determination is YES, that is, if a capital letter r-ta is specified, the capital letter flag (LCF) 221 is turned on (step L8), and the process advances to step L9. On the other hand, step L
If the determination in step 7 is No, the process directly advances to step L9. In step L9, ")" which is the end of the definition of the data attribute (end of the data stripe designation field) is skipped.

Subsequently, in the next step L1.0, the delimiter "," of the input command is deleted, and the process proceeds to step Lll. In this step Lll, the main memory 20 (program working area 24) +
The address of the 7i area is determined according to the character (variable) next to ",".

Note that if the determination in step L3 is No, that is, if the data attribute is not defined, the process of step Lll is directly performed.

When the processing of Stella 7'L11 is completed, the manual data from KR50 is transferred to the key buffer (key buffer) prepared in the system working area (5XAlA) 22 of the main memory 20.

) is performed. In this data import process, as shown in the flowchart of FIG. 6, first, B 5
Characters from 0 to 1 are manually input (step r, 121), ! 1
Then, it is determined whether the input sentence is a carriage return code (step L122).

If this determination is No, the numerical flag (NF') 22
2 is turned on (that is, whether numeric data is specified or not) is determined (step L123).
). If the determination in step L123 is YES, it is determined whether the input character in step L121 is a number (0 to 9) (step L124). Step L12
If the determination in step 4 is YES, the input characters are stored in the key buffer prepared in the system working area (SWA) 22 (step L125), and then the characters are stored in Stella: 7'l, 121. return. On the other hand, if the determination in step L124 is No,
The human input characters in step L121 are ignored and the process returns to step L121. As in this example, ATTR(”
In the case of an INPUT command in which “D”) is written,
As mentioned above, step L6 in the flowchart of FIG.
The numerical flag (NF) 2.22 is turned on. Therefore, in the data import process of FIG. 6, only numeric input characters are stored in the key buffer. On the other hand, step L
If the determination of 123 is No, the uppercase flag (LCF
) 227 is on (that is, whether uppercase alphabetic character data is specified).
Step Ll 26). If the determination is No, the process proceeds to the input data storage process of the previous 6C step 7'L125, and if the determination is YES, the process proceeds to step L127 for determining whether the input character is a lowercase English letter. If the determination in step L127 is No, the process proceeds to the input data storage process of step L125, and if the determination is YES, the process proceeds to step L125 via the step L128 where I capitalize human-powered characters (U!). .

The above operation is repeated, and when the determination at step L122 becomes YgS (that is, when it is detected that the carriage return key of KB50 has been operated), the data import process of FIG. 6 (that is, the step of FIG. 5 Step L12) ends, and the process proceeds to step L13 in FIG. In step L13, the contents of the key buffers Ir:i, . . . Ai5 are stored in the area within the program working area (PWA) 24 indicated by the data storage address set in step Lll. When the process of step L13 is completed, the next character (that is, the character next to the variable in the INPUT script) is 1. '', and whether there is anything that still needs to be done manually in the month 1j is determined (step L14).

If this determination is a YKS determination, the steps LLl to L
14 is executed again, and if the judgment is No, the execution processing of the statement in FIG. 5 (ie, step L in FIG. 4) is completed.

When the sentence execution process (step L) is completed, the step is determined as described above. If the judgment for the step is N Oil 7, go to steps L and K again.
is executed. child! On the other hand, the decision to step is YES.
If the determination is positive, a program termination process (step M) is performed, and control is transferred to one-line manual processing (stellar fk).

〔Effect of the invention〕

As described in detail above, according to the present invention, the consistency check of input data with a program can be performed without preparing a special instruction for checking. Therefore, it is possible to simplify a program including input commands, which is created in the form of an input computer program from a human-powered device. Unfortunately, according to this invention, the above-mentioned plasticity check is performed at the time of data input, which reduces the possibility of input errors.
