Description

[Detailed Description of the Invention] [Summary] In automobile sales operations, the processing operations differ depending on the location such as head office, sales office, etc., and therefore the types of input/output devices that input and output business data also differ. Therefore, in addition to the location classification, by specifying the model that indicates the required functions and performance, the type of terminal is specified for both the input device and the output device. Therefore, the terminal and its type can be uniquely defined by configuring the terminal name by the installation location, location classification, input/output, and model. Therefore, according to the terminal name of the present invention, when the terminal name of one of the input or output devices of the terminal is specified, it can be handled by replacing the codes assigned to the input device and the output device of the input/output section with each other. You can specify the other. Furthermore, the processing routine of the corresponding application program is determined by the location classification.

[Industrial application field]

The present invention relates to a connection between an application program and a terminal using a line management program (communication access method, etc.) of a center computer of a data communication system, and particularly relates to a method for specifying a terminal name.

2. Description of the Related Art In recent years, data communication systems that centrally process and manage information by inputting information generated at a remote location into a terminal and transmitting it to a central computer via a line have been adopted in all kinds of industries. However, when different types of processing tasks exist in a data communication system, different terminals suitable for the tasks exist, and application programs are required to have multiple processing routines.
For example, in the automobile sales business, the operations handled and the terminals used differ depending on the dealership's head office, sales office, and departments such as the engineering department and accounting department, and therefore the processing of application programs also differs. Further, for example, when outputting the results of processing by a computer to a terminal, the output device is required to have the same type of data format as alphanumeric characters, kana characters, kanji, etc., and other functions as the type of input device. Therefore, depending on the terminal name,
You can specify the output device that corresponds to the terminal input device,
There is also a need for a terminal name designation system that can identify the corresponding routine of an application program.
