Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a console message output length control method;
In particular, the present invention relates to a console message output control method for controlling the output length of an output message output by executing a message output command to a console in a user program.

[Conventional technology]

Conventionally, in this type of console message output control method, when controlling the message output length to the console, the user specifies a variable length item as the output target in the message output command to the console in the user program. The amount of messages output to the console was controlled by changing the length of variable-length items in combination with conditional commands.

[Problem to be solved by the invention]

In the conventional console message output amount control method described above, the length of the variable-length item to be output must be changed in combination with a conditional command in the user program. The disadvantage is that the number of lines increases.

Additionally, generally, variable-length items and conditional commands are not written in user programs, and only message output instructions to the console are written, so messages are output to the console using the entire length of fixed-length items. Therefore, in large-scale computer systems, the console is in a state of waiting for output, which has the disadvantage that effective computer system operation cannot be achieved.

In view of the above points, an object of the present invention is to enable the maximum amount of messages to be output to the console to be specified using a job control language, thereby eliminating the need to increase the number of development steps and lines of a user program. You can reduce the amount of output messages to the console,
As a result, it is an object of the present invention to provide a console message output amount control method that can eliminate the waiting state for outputting messages to the console in a large-scale computer system, and can achieve detailed operation of the computer system.

Means for Solving the Problem] The console message output amount control method of the present invention provides a message output amount instruction that inputs message output amount instruction information written in a job control language that instructs the execution of a user program. an information input means, a console message text input means for inputting a console message text consisting of an output message and a message output amount generated as object data of a command to output a message to the console in a user program; and this console. The message output amount of the console message text input by the message text input means is compared with the message output amount instructed by the message output amount instruction information inputted by the message output amount instruction information input means, and the message output amount is determined. If it is larger than the instruction message output amount, the instruction message output amount is used, and if the message output amount is equal to or smaller than the instruction message output amount, the message output amount is used as the output message of the console message text. console message text output amount determining means for outputting the text to the console.

[Effect]

In the console message output amount control method of the present invention, the message output amount instruction information input means inputs message output amount instruction information written in a job control language that instructs execution of a user program, and the message output amount instruction information input means inputs a console message text consisting of a message output amount and an output message generated as object data of a message output command to the console in the user program, and the console message text output amount determining means uses the console message text input means. The message output amount of the input console message text is compared with the instruction message output amount instructed by the message output amount instruction information inputted by the message output amount instruction information input means, and if the message output amount is larger than the instruction message output amount. For example, if the message output length is equal to or smaller than the instruction message output amount, an output message of the console message text is output to the console at the message output amount.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a console message output amount control system according to an embodiment of the present invention. , a console message text input means 2, a console message text output determination means 3, a console 4, and a main storage device 5.

The main storage device 5 includes a message output length instruction information storage area 5
1 and a console message text storage area 52.

The message output length instruction information storage area 51 specifies the maximum message output length of an output message to the console, which is written in the job control language that instructs the execution of the user program, when a user program (not shown) is executed. Message output production instruction information is stored. Hereinafter, the maximum message output length specified by the message output length instruction information will be particularly referred to as the instructed message output length.

The console message text storage area 52 stores console message text generated as object data of a message output command to the console 4 in the user program.

FIG. 2 is a diagram showing the structure of the console message text stored in the console message storage area 52. This console message text is composed of a message output length, which is, for example, 4-byte numerical data, and an output message having the size of the message output length.

Referring to FIG. 3, the processing in the console message text output length determination means 3 includes an output message length/indication message output comparison step 31, an output message output step 32 at the instruction message output length, and a message output length comparison step 31. and an output message output step 33.

Next, the operation of the console message output length control system of this embodiment configured as described above will be explained.

When a job control language is input that instructs the execution of a user program (not shown), the operating system (
(not shown), the job control language is analyzed and the execution of the user program is started, and at the same time, the instruction message output length of the output message to the console 4 written in the job control language is specified as message output instruction information. It is stored in the message output length instruction information storage area 51.

When a command to output a message to the console 4 in the user program is executed after execution of the user program is started according to instructions from the job control language, the console message text is output as object data of the command to output a message to the console 4. It is generated and stored in the console message text storage area 52.

When the console message text is stored in the console message text storage area 52, the message output length instruction information input means 1 is activated and inputs the instruction message output length from the message output instruction information storage area 51.

The console message text input means 2 also inputs console message text from the console message text storage area 52.

Next, console message text output length determining means 3
The message output length in the console message text input by the console message text input means 2 is compared with the instruction message output length input by the message output length instruction information input means 1, and the message output length is determined as the instruction message output ratio. If the message output length is larger than the command message output length (step 31), the console message text output length determining means 3 determines whether the message output length is larger than the command message output length (step 31). The message is output to the console 4 (step 32). If the message output length is equal to or smaller than the instruction message output length, the console message text output determination means 3 outputs the output message in the console message text to the console 4 using the message output length in the console message text. Output (step 33).

C Effects of the Invention As explained above, the present invention enables the execution of a message output command to the console by allowing the maximum message output length of a message to be output to the console to be specified in the job control language as the instruction message output length. You can sometimes reduce the amount of messages output to the console,
As a result, it is possible to eliminate the waiting state for outputting messages to the console in a large-scale computer system, and it is possible to perform detailed operation of the computer system.

In addition, it is possible to eliminate the need to specify a variable length item as the output target in the message output command to the console in the user program and change the length of the variable length item by combining it with a conditional command. This has the effect of reducing the number of man-hours and the number of lines in the user program.
