CONSTITUTION:When data consisting of the length of the symbol string interposed between symbol string start control code information and symbol string end control code information is inputted, a symbol string length calculating processor 2 counts the length of the symbol string and adds the symbol string start control code of the start of the symbol string to the result, and a series of data are transferred to a processor 3 for shaping and arrangement. If the data length exceeds a preliminarily determined value, data is delimited temporarily there though following data exists, and the symbol string start control code like X infinity is added to the end of the calculated value, and a series of data till then are transferred to the processor for shaping and arrangement, and remainder data is counted.

Description

[Detailed Description of the Invention] [Summary] A data string containing a mixture of character symbols constituting a program, symbol string start control code information and symbol string end control code information determined for formatted output is input, and these data strings are input. is processed in parallel by a processor that counts symbols in a symbol string sandwiched by separately provided control codes, and a processor that performs formatting and arrangement based on the control code and the length of the symbol string. The present invention discloses a high-speed program formatting output device that quickly outputs a formatted program list without having to read or write a formatted program list.

[Industrial field of use] Relating to a device that outputs an unreleased date L± program list in an array that correlates to the fdlal 旙灓 of Ki, especially for generating programs or outputting a program list without depending on a programming language. The present invention relates to a high-speed program formatting output device that can be incorporated into a system.

[Prior Art] A program consists of statements such as instructions for operating an electronic computer. In particular, many high-level programming languages that are expanded into machine language by a compiler allow programs to be written in a free format.

However, when decoding a program, it becomes extremely difficult to decode a program if the statements are listed without regard to the control structure. Therefore, conventionally, in systems that generate and display programs, in a certain processing unit,
Programs are formatted and output using line breaks and line breaks.

However, in such a method, the formatted output function of the program is not clearly separated from other parts such as syntax analysis, so the part that performs formatted output depends on the programming language, and is different for each target programming language. had to be rebuilt.

Therefore, by setting a control symbol that has information regarding formatting related to the output array and inserting this formatting control symbol into the symbols that make up the program, processing that depends on the programming language and programming language A device is being considered that is capable of performing versatile processing for formatting and outputting a program list by separating the processing from formatting and outputting an independent program.

[Problems to be Solved by the Invention] The device for obtaining a formatted output of a program list through independent processing without depending on the programming language described above is
Input a data string containing a mixture of character symbols that make up the program, symbol string start-control code information, and symbol string end control code information determined for formatted output, and generate a symbol string sandwiched by these control codes. The length of the data is counted and the formatted output is controlled based on that value, but the processing speed is slow because processing related to the formatted output cannot be performed until the counting of the series of data is finished. There was a problem.

SUMMARY OF THE INVENTION In view of the above conventional problems, an object of the present invention is to provide a processing device that can output a formatted program list at high speed.

[Means for Solving the Problems] According to the present invention, this object is achieved by using character symbols constituting a program and a symbol string start control code defined for formatted output. A data processing device that inputs a data string in which information and symbol string end control code information are mixed and outputs a program source list, the data string being sandwiched between the number string start control code information and the symbol string end control code information. A symbol string length calculation processor that counts the length of a symbol string, and a formatting processor that outputs a series of symbol strings according to a specified array format. When counting is completed, the counted value is added, and when the symbol string length exceeds a predetermined value, information indicating that fact is attached to the symbol string start control code of the corresponding symbol string, and formatted each time. This is achieved by a high-speed program formatting output device characterized in that the processor for symbol string length calculation and the processor for formatting and arranging perform parallel processing when the processor for locating processes the corresponding data.

[Operation] In the apparatus of the present invention, when data consisting of a symbol string length sandwiched between symbol string start control code information and symbol string end control code information is input, the symbol string length calculation processor calculates the symbol string length. The receiver counts the length and attaches the result to the symbol string start control code at the beginning of the symbol string, and passes the series of data to the formatting processor. At this time, the data length is set to a predetermined value (for example When the value of the formatted output width is exceeded, even if there is a continuation of the data, separate the data at that position and add a sign, such as +ω, to the symbol string start control code instead of the count value. , the series of data up to that point is passed to the processor for formatting and placement. Subsequently, the remaining data is counted. As a result, the symbol string actual calculation processor and the formatting/arranging processor operate in parallel, and the processing time is shortened, especially when processing long data.

[Embodiment] FIG. 1 is a block diagram of an embodiment of the present invention, in which 1 is an input controller, 2 is a string calculation processor, 3 is a formatting and arranging processor, 4 is an output controller, 5 is an output buffer, 6 represents an input buffer.

FIG. 2 is a diagram illustrating formatted output, and (a)
shows an example of a formatted output list, and (b) shows (
FIG. 3 is a diagram showing the correspondence of formatting control symbols to the output shown in FIG.

In FIG. 2, 7 to 18 represent shaping control symbols.

The operation of the system shown in the block diagram of FIG. 1 will be explained below.

In FIG. 1, a character string length calculation processor 2 calculates each size of data (a character symbol string with formatting control symbols) as shown in FIG. 2(b) sent from an input controller 1. The sum of the character and symbol strings inside the parentheses (formatting control symbols) is calculated and added to the friend parentheses as additional information. At this time, if the sum of the character and symbol strings exceeds the formatted output width, "÷■" is given to the friend brackets as the additional information, and the character and symbol strings are processed as having been found.
The character string length calculation processor 2 outputs the additional information (both character and symbol strings or +■) for the input friend brackets to the output buffer 5 in the order of the input characters and symbols as soon as it is determined.

The formatting and arranging processor 3 receives the data in the buffer 5 via the input buffer 6, performs formatting and arranging processing based on the formatting control symbol and additional information, and passes the result to the output controller 4 to output the data. Controller 4 outputs this.

In this way, regarding the formatting and arrangement processing that conventionally could only be executed after calculating the character string length, the present invention allows the formatting and layout processing to be performed on the target (card puncher, line printer, etc.) that performs formatted output.
By focusing on the fact that the output width is fixed, the character string length calculation processor separates character strings that are larger than the corresponding output width once the output width has been counted. By giving the additional information "+■", the data is separated from the following data and output, and the formatting and arranging processor formats and arranges the data sequentially from the beginning and outputs it.

To further explain the shaping arrangement, the above-mentioned figure 2 (b

In addition, to explain the above-mentioned additional information, Fig. 2 (b
), the character and symbol strings between formatting control symbols 7 to 18 should originally contain the sum of all character and symbol strings, but in this invention, the sum of the character and symbol strings is calculated in order from the beginning. During the calculation, when the value exceeds the output width (predetermined value), "+■" is used as the value to delimit the data. (The display of "+(1)" has the meaning that it is impossible to fit within the output width.) Figure 2 (b
), the range (unit) surrounded by the shaping control symbols 8 to 15 is also treated as "+ω". Other shaping control symbols 9, 10.11, 12.13 and 14.1
For units of 6 and 17, the actual count value of character symbols is added as additional information.

An example of the processing procedure in such a character string length calculation processor in this embodiment is shown as a flowchart in FIG.

[Effects of the Invention] As explained above, according to the present invention, by inputting a data string in which character symbols constituting a program and symbol string start and end control code information determined for formatted output are mixed,
When performing data processing to output the source list of the program, calculation of character symbol string length and formatting for list output are processed simultaneously in parallel, resulting in faster program generation and processing. The effect is great because it is possible to realize a device that outputs a list.
