Abstract

PURPOSE:To enhance the efficiency of desk debugging by making the programming point easy to catch, especially, on a program list by facilitating the discrimination between a character string and the other part, by searching for a predetermined charac ter string from the character string data outputted from an output device and applying emphasis processing to the part of said character string to output the same. CONSTITUTION:For example, 'AA' is entered in a designated word table as a designat ed word and a character string search part 2 is equipped not only with a pushup stack 4 for referring to the designated word but also with an output route 5 for outputting emphasized character string data and a route 6 for outputting the character data as it is without emphasizing the same. At first, one character data is taken out from input data to be set to the first bite of the stack 4 of the character string search part 2 and, next, the next one character data is taken out from the input data to be set to the second bite of the stack 4. The content of the stack 4 is compared with the designated word data of the designated word table 1 and, when the data of the stack 4 is 'AA', the first and second bites of the stack 4 are successively taken out in a character string replacing part 3 and altered to an emphasized character to be outputted from the output route 5 and the stack 4 is cleared to advance the processing of the next character string data.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a character string emphasis output method in a computer system, and in particular, to a method for automatically emphasizing a predetermined character string in output character string data such as a program list. This invention relates to a character string emphasis output method that performs processing and outputs.

[Prior Art 1] In desktop debugging, which is one of the basic and effective methods for debugging programs, a program list written in a programming language is used.

[Problems to be Solved by the Invention] By the way, this list is usually written using a single type of characters, making it difficult to distinguish language reserved words, variable names, etc. Therefore, if the programmer is unfamiliar with the language, he or she may not be able to remember reserved words, which is the key point of programming, and this may cause problems such as debugging not progressing or incorrectly determining that the program is correct when it is incorrect. Ta. Furthermore, if the programmer wanted to refer to this list and focus on a particular variable, he had to mark it himself using a marker or the like.

In view of the above-mentioned problems of the conventional method, an object of the present invention is to emphasize a predetermined character string such as a designated word or a reserved word in various outputs from a computer system, thereby making the character string stand out and other parts. The purpose is to make it easier to distinguish between the two, and to make it easier to identify programming points especially on the program list, thereby increasing the efficiency of desktop debugging.

[Means and effects for solving the problems] In order to achieve the above object, the character string emphasis output method of the present invention is provided in a computer system equipped with an input device, an output device, a storage device, and a central processing unit. The present invention is characterized in that a predetermined character string is searched for in character string data outputted from an output device, and the predetermined character string portion is emphasized based on the search results before being output.

This allows the predetermined character string to stand out in the character string data that is the output result.

This predetermined character string may be externally designated as a specified word, or may be a predetermined reserved word.

Further, the output device can be a display device such as a printer or a CRT. If the output device is a printer and the character string data to be output is a program list, a predetermined character string that is a key point during debugging can be distinguished from other parts on the program list.

[Example] Hereinafter, the present invention will be explained in detail using the drawings.

The character string emphasis output method of the present invention can be realized, for example, by equipping a normal computer system with a character string search section, a character replacement section, and a specified word table.

FIG. 1 shows the constituent parts of a system to which a character string emphasis output method according to an embodiment of the present invention is applied. In the figure, reference numeral 1 denotes a designated word table, in which character strings to be emphasized specified in advance by the user are registered. Reference numeral 2 denotes a character string search unit, which searches and checks whether or not a designated word is included in input character string data while referring to a designated word table. Reference numeral 3 denotes a character string replacement unit, which changes a designated character string portion to a highlighted character based on the result of the check performed by the character string search unit.

In the above configuration, assume that program list data as shown on the left side of FIG. 2 is given as input data. At this time, if rAAJ is registered as a specified word in the specified word table, output data as shown on the right side of the figure will be output. It can be seen that the designated word rAAJ is highlighted in bold.

Next, the procedure for emphasizing the specified word rAAj as shown in FIG. 2 will be described with reference to the configuration diagram in FIG. 3 and the flowchart in FIG. 4.

In Figure 3, designated word table 1 contains r as a designated word.
AAJ is registered. The character string search unit 2 also includes a first-in, first-out stack 4 for searching for specified words. In addition, 5 is the output route of the highlighted character string data,
6 shows a route in which the input data is output as is without being emphasized.

In FIG. 4, first, in step S1, one character data is extracted from input data, and in step S2, it is checked whether the extraction was successful. If the extraction fails, the process is terminated, and the process returns to the beginning and starts from step S1. If one character is extracted, this character data is set in the first byte of stack 4 of the character string search section in step S3.

Next, in step S4, the next character data is extracted from the input data, and in step S5, it is checked whether the extraction was successful. If the extraction fails, the process branches to step S7. If the retrieval is successful, this character data is set in the second byte of the stack 4 of the character string search section in step S6.

In step S7, the contents of stack 4 and specified word table 1 are
Compare specified word data. Here, the designated word is rA
Since AJ is registered, the contents of star 4 and this r
This will be compared with AAJ.

If the data in the stack 4 is rAAJ in step S7, the process branches to step S8, and the character string replacement unit 3 extracts the first byte of the stack 4, changes it to an emphasized character, and outputs it from the output route 5 in FIG. do. Similarly, in step S9, the second byte of the stack 4 is taken out, changed to an emphasized character, and outputted from the output route 5 in FIG. next,
The stack 4 is cleared, and the process returns to step S1 to proceed with the processing for the next character string data.

On the other hand, if it is determined in step S7 that the data in stack 4 is not rAAJ, in step 811 the first byte of stack 4 is output from the output router shown in FIG. Furthermore, in step 312, the data of the second byte of stack 4 is set to the first byte, and in step 813, the data of the stack 4 is set to the first byte.
Clear the second byte of. In step 314, it is determined whether character data exists in the stack 4. If character data exists, the process branches to step S4. stack 4
If there is no character data, the process ends, and if there is still input data, the process starts again from step S1.

The above process is repeated to emphasize and output the designated word.

Note that in this embodiment, the output data is emphasized by making it bold, but the emphasizing process is not limited to this, and various other emphasizing processes can be applied. For example, the font, color, or size of the characters may be changed, or when output to a display device, the characters may be highlighted by blinking or the like.

According to this embodiment, the character string specified by the user is highlighted, making it easier to focus on a specific variable. In addition, errors in typing variables, etc., become easier to discover.

In addition, instead of or in addition to the specified word table in this embodiment, a reserved word table in which reserved words are registered is provided and these are emphasized.The reserved words will become more noticeable and cause syntax errors. It also makes it easier to spot typos.

In general, the character string emphasis output method of the present invention is applied to computer systems, but it can also be applied as a filter to UNIX (trade name of O8 developed by AT&T Bell Laboratories), which is the O8 that has been frequently used in recent years. By configuring this, predetermined emphasis processing can be easily performed on character string data handled on tJNIX, which is convenient.

[Effects of the Invention] As explained above, according to the present invention, in a computer system, a predetermined character string is searched from character string data output from an output device, and a predetermined character string portion is searched based on the search result. Since the character string is output after being emphasized, the character string stands out and can be easily distinguished from other parts, making it easier to identify programming points, especially on the program list, and improving the efficiency of desktop debugging.
