The logon processing program 3 controls the communication between the communication control program 5 of its own computer and the other computer to communicate with the application program 6 in the other host computer 2 using the logical communication path 8 specified by the user. The information is transmitted to the control program 7. The communication control programs 5 and 7 perform communication between the terminal 9 of the terminal 9 and the application program 6 of another device. At this time, it is necessary that the logical communication path 8 is not already occupied by another terminal 9 or the like for data communication.

[Problem that the invention seeks to solve]

Conventional logon processing is performed as described above, so the user must know the names of all logical communication paths 8 in advance and specify them in the logon command. There is a problem in that it is sometimes necessary to check in advance which unused logical communication paths 8 are available.

This invention was made to solve the above-mentioned problems, and it eliminates the need for users to be aware of logical communication paths, and also allows users to connect to other host computers by omitting logical communication path names and using short logon commands. The purpose is to obtain a logon processing method that allows access to .

[Means for solving problems]

In this invention, a logon processing program 3 and a management table 10 managed by the logon processing program 3 are formed in the computer 1, and each record of the logical communication path 8 is registered in this management table 10, and this registered A flag register f corresponding to the name and indicating whether it is in use or not is provided, and the logon processing program 3 refers to the flag register f to determine one of the logical communication paths 8 to be used.

[Effect]

When there is an access request from the terminal of the computer 1 to another computer 2, the logon processing program 3 searches the flag register f in the iFl table 3 and uses an unused logical communication path 8.
Find one of them, specify its name, and set up a communication path. In this way, the logon processing program 3 can obtain management information regarding the logical communication path 8 from the management table 10.

〔Example〕

A first embodiment of the invention will be described below with reference to the drawings. In FIG. 1, 1 is the host computer, 2 is another host computer, 3 is a logon processing program that performs logon processing to other host computers, 4 is an application program in the host computer, 5 is a communication control program, and 6 is a communication control program. Application program in another host computer, 7 is a communication control program, 8 is a logical communication path consisting of multiple paths set between the own host computer 1 and other host computer 2, 10 is a management table for the logical communication path 8 , 9 are a plurality of terminals managed by the host computer. The management table 10 is equipped with a plurality of flag registers f in one-to-one correspondence with each logical communication path 8, and is set to 1 for a logical communication path 8 that is in use, and is set to 1 for an unused logical communication path 8. 0 is set respectively. The logon processing program 3 manages the management table 10, and sets and resets each flag in the flag register f.

Application program 42 Communication control program 5. The logon processing program 3 and the management table 1 o foil 2 The application program 6 and the communication control program 7 of the own host computer are generated by software in each main memory of the other host computer 2, or are created in the hardware by a microprogram. The logical communication path 8 is defined as a bundle formed as follows.

Next, the operation of the first embodiment will be explained according to the flowchart shown in FIG. First, when each program is generated, each name of the logical communication path 8 is registered in the management table 10 in advance. 6, access
