Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character output device, and particularly to a character output device capable of storing system logging messages in an external storage device M.

[Prior Art] In conventional devices of this type, search means for printing out system logging messages stored in an external storage device include 1) specification by the creation date of the system logging message; Specifying system logging messages by time of occurrence;
Required system logging messages were selected by specifying message type and level, and output processing was performed.

[Problem to be solved by the invention] However, with the above-mentioned search means, only the date, time, and message level can be used.
Only combinations of selections using two keys are allowed, and it is not possible to focus only on a specific message, search for only the specified message, and print it out. Only messages have to be extracted, which is cumbersome and inefficient, and is not always satisfactory in terms of use.

The present invention has been made in view of the above-mentioned prior art, and it is an object of the present invention to provide a printing device that can print out a necessary portion of a system logging message without manual editing.

[Means (and effects) for solving the problem] As a means to solve this problem, for example, in this implementation, a message table in which system messages are given unique numbers is maintained in the system. , a parameter meaning a system message number is added to an operation command for instructing the system to print out a system logging message.

[Example] Figure 1 shows the system message table structure,
Figure 2 shows the external memory f, the system information stored in the @device, and
It is in the form of one logging message. The operator can enter the date, hour range, level, and
Specify each message number. In FIG. 3, when one message is read from the external storage device, information as shown in FIG. 2 is obtained. It is determined whether or not to output a message depending on the presence or absence of parameter specification, and if the message matches the specified conditions, it is transferred to the output expansion routine. This makes it possible to obtain a printout of system logging messages without having to focus on and manually search for specific system messages.

[Effect of the invention] As explained above, according to the present invention, the operation
By adding a parameter indicating a message number to the command, a printout of the system logging message most needed by the operator can be easily obtained without manual intervention.

[Brief explanation of the drawing]

FIG. 1 is the structure of a system message table stored in RAM or external storage. FIG. 2 is the format of system logging messages saved in external storage. The message number and the time of occurrence have a fixed length, and the additional information that is always present assists the content of the basic message, and the length of the message is variable, with terminators separating each message. FIG. 3 is a flowchart from when the message is read until it is transferred to the output routine.

Claims (1)

[Claims] A character output device characterized in that a search method using a system message number is enabled as a means for outputting a system logging message.
