Abstract

PURPOSE:To read out the message at high speed without executing a text retrieval with an error number by applying a prescribed arithmetic processing to the error number, and deriving clearly a table address of an error message. CONSTITUTION:When an error number is received, a compiler 1 checks whether its error number exists in a built-in error number table 1a or not. When the error number exists, the error number is read out and inputted to an arithmetic circuit 20. The arithmetic circuit 20 denotes the error number concerned as (i), for instance, executes the conversion of (i-1) X 4 and derives the reference address of an error message number table 10. This reference address is deter mined clearly, and an address of a text corresponding to the reference address is determined. Subsequently, the compiler 1 executes an access to the area concerned of an error message text table 11 from the read-out text address.

Description

[Detailed Description of the Invention] [Summary Regarding the message body output method for outputting message bodies such as co-error messages, the purpose of this is to speed up the reading of error message bodies and make effective use of memory. It is equipped with a compiler that stores error numbers, an error message number table that stores the message body and its address, and an error message body table that stores the length and message body of the message at the address corresponding to the address of the body. When outputting a message, the error number is subjected to predetermined arithmetic processing to uniquely find the address where the message body is stored, and the error message body is generated based on the body address read from the error message number table corresponding to that address. It is configured to access the table and read the corresponding message body.

[Industrial Field of Application] The present invention relates to a message body output method for outputting a message body such as an error message.

In recent years, with the enhancement of message services related to errors when using software, etc., the output of message bodies has been curtailed, but there has been a demand for the accumulation of large amounts of messages and for faster services.

[Prior Art] FIG. 4 is an explanatory diagram of a conventional method for outputting an error message. 1 is a compiler, which includes an error number table 1a in which error numbers are stored. 2 is an error message table in which error message texts are stored in pairs with error numbers. In the system configured as described above, when an error message number is input, the compiler 1 searches the error message table 2 using a method such as a binary search method based on the manually entered error number. Then, the error message table 2 corresponding to the found error number is accessed and the message text contained in the corresponding address is read.

[Problems to be Solved by the Invention] In the conventional method, it took a very long time to search the error message number from the error number table 1a. Furthermore, in the conventional system, the size of the area for storing the message body is fixed to a size that matches the maximum length of the message. Therefore, when a short message is stored, the free space is wasted.

The present invention has been made in view of these problems, and an object of the present invention is to provide a message body output method that can speed up the reading of the error message body and make effective use of memory.

[Means to solve the problem] FIG. 1 is a block diagram of the principle of the system of the present invention.

Components that are the same as those in FIG. 4 are designated by the same reference numerals.

In the figure, 1 is the compiler in which the error number is stored in the error number table 1a, 10 is the error message number table in which the address of the text is stored in the address corresponding to the error number, and 11 is the compiler in which the address corresponding to the text is stored. This is an error message body table that stores the length of the message body and the message body.

[Function] When outputting a message, the target error number is referred to from the error number table 1a, a predetermined calculation process is applied to the error number, and the message is uniquely output from the error message number table 10.
The error message text table 11 is accessed based on the text address read from the error message number table 10 to read the corresponding message text. According to the present invention, a message can be read without performing a text search using an error number, so that processing speed can be increased and memory requirements can be reduced.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a block diagram showing an embodiment of the present invention. Components that are the same as those in FIG. 1 are designated by the same reference numerals. In the figure, 1 is a compiler, which includes an error number table 1a for storing error numbers. 20
is an arithmetic circuit that performs predetermined arithmetic processing on the error number read from the error number table 1a to obtain an address. The output of the arithmetic circuit 20 accesses the portion of the error message number table 10 at the same address.

As described above, the error message number table 10 is composed of pairs of addresses and text addresses. Here, as each text address, the first address of the address where the message text is stored is written.

The text address read from the error message number table 10 accesses the address of the error message text table 11. Error message body table 11
As shown in the figure, the message consists of a part indicating the length of the message and the message body. In this way, by storing the length of the message and the body in pairs, the portion where the message body is stored can be made into a variable length area, and memory can be used effectively. In other words, according to the present invention, as shown in FIG. 3, combinations of length and message text can be stored in a continuous manner, so there is no waste of memory. In other words, memory can be used effectively. The operation of the system configured as described above will be explained as follows.

When the compiler 1 receives an error number, it checks whether the error number exists in the built-in error number table 1a. If an error number exists, the error number is read out and input to the arithmetic circuit 20 manually. Arithmetic circuit 2
0, when the error number is entered manually, the reference address of the error message number table 10 is obtained by performing a conversion operation such as (i-1)X4, using the error number as i.

This reference address is uniquely determined, and the address (first address) of the text corresponding to the reference address
is determined.

Then, the compiler 1 accesses the corresponding area of the error message text table 11 from the read text address. The error message body and length information of the message are stored in that area. Here, the compiler 1 reads and outputs information corresponding to the length. In other words, the information corresponding to the length stored at the beginning of the error message body table 11 becomes the length of the message body. According to the present invention, error message body table 11. Since there is no need to perform a search as in the conventional method when reading out error message information from the system, the time required to read out the message information is significantly reduced. Therefore, according to the present invention, a message can be read without performing a text search using an error number, so that processing speed can be increased and memory requirements can be reduced.

In the above description, the case where an error message is outputted has been explained as an example, but the present invention is not limited to this, and can be similarly applied to the case where other types of messages are outputted.

[Effects of the Invention] As explained in detail above, according to the present invention, an address and a text address are stored in the error number table included in the compiler, with the error number subjected to a predetermined operation as an address. It is possible to uniquely access the error message number table stored in the error message number table and access the error message text table from the read text address, thereby speeding up processing and reducing memory requirements.
