Abstract

PURPOSE:To start a user program without preliminarily registering the name of a transfer object file (start condition) and the name of a file (start information) which corresponds to it and where the user program to be started is stored. CONSTITUTION:After the end of file transfer, a part ('ABC') of the name of a transfer object file 7 is extracted from the name of the transfer object file 7 and an extender (the name indicating the classification of the file) 'LOD' indicating an execution program is added to this part to obtain another name in accordance with a certain conversion rule. For example, name 'ABC.LOD' is obtained when the name of the transfer object file is '!ABC0O01.DAT'. This obtained name is used as the name of a file 10 where the user program is stored; and when the pertinent file exists, it is not started unless the user program 11 is started.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a system configuration diagram of this embodiment.
The computer system 1 and the partner computer system 2 are connected by a line 3. The computer system 1 is executing a (resident) type file transfer program 4 that waits for a file transfer instruction, receives the name of the transfer target file 7 and the transfer instruction (transmission or reception instruction), and transfers the file. The file 7 is read and transmitted to the partner computer system 2, or the data received from the partner computer system 2 is stored in the transfer target file 7. Then, the name of the file 10 storing the user program is obtained from the name of the transfer target file 7 based on a certain conversion rule, and the start program 9 is requested to start the user program. The startup program 9 is the file 1 that stores the user program.
0 is read and the user program 11 is started. On the other hand, in the partner computer system 2, the file transfer program 5 is executed, the name of the transfer target file 8 and the file transfer instruction (transmission or reception instruction) are input from the terminal device 6 and transmitted to the computer system 1. Then, the file 8 to be transferred is read and transmitted to the computer system 1, or the data received from the computer system 2 is transferred to the file 8 to be transferred.
Or store it in.

FIG. 2 shows an example of conversion rules for obtaining the name of the file 10 storing the user program from the name of the transfer target file 7. Name of file to be transferred 71
Is composed of a program activation identification 72, a program name 73, an arbitrary name 74 and an extension 75. When the program activation identification 72 is "!", The user program is activated, and the user program The name 101 of the file in which is stored is calculated. The method is program name 73
Extract this and use it as the program name 102.
It is to add the extension 103 "OD". The arbitrary name 74 “yyy” and the extension “zzz” are not used for conversion. When the program start identification 72 is not "!",
The user program is not started, and the name 101 of the file storing the user program is not required. By doing this, for example, the name of the transfer target file is "! A.
BC0001. In the case of "DAT", the name of the file storing the user program is "ABC.LOD".

FIG. 3 is a flow chart of the file transfer program 4 of the computer system 1. The file transfer program 4 is the partner computer system 2 connected by the line 3.
The transfer instruction (transmission or reception instruction, and the name of the transfer target file 7) from the file transfer program 5 is waited (41). An operator who wants to transfer a file gives a transfer instruction from the terminal device 6. The transfer instruction is passed from the file transfer program 5 to the computer system 1 through the line 3 and is received by the file transfer program 4. (42).
As a result, the transfer target file 7 of the computer system 1
And the transfer target file 8 of the partner computer system 2 is executed (43). When the file transfer is completed,
The file transfer program 4 obtains the name of the file 10 storing the user program using the conversion rule of FIG. 2 (44). As a result, if the name is obtained, the obtained name is passed to the activation program 9 and the user program activation request is made. If the name is not obtained, the activation request is not made (45, 46).

FIG. 4 is a flow chart of a process in the file transfer program 4 for obtaining the name of the file 10 storing the user program from the name of the transfer target file 7 according to the conversion rule of FIG. First, the first character of the transfer target file name is extracted (4401). Top 1
If the character is "!", Extract the next three characters (440
2,4403), with ".LOD" added (440
4) The obtained name is set as the name of the file storing the user program (4405), the return code is set as "acquire user program name" (4406), and the process returns. If the first character is not "!", The return code is set to "Don't acquire user program name" (4402,
4407), and return.

FIG. 5 is a flowchart of the startup program 9. The startup program 9 is the file transfer program 4
Find the file corresponding to the name given by (9
1) If there is a corresponding file, the file is read and the user program is started in the computer system 1, and if not, it is not started (92, 93).

As described above, the name of the file 10 storing the user program corresponding to it is obtained from the transfer target file 7, and the target user program is started. Therefore, the transfer target file 7 (start condition) And the name of the file that stores the user program 10 (startup information)
It is not necessary to register in advance.

In this example, the leading "!" In the name of the file to be transferred is used to identify whether or not the user program is to be started (the object to be started), and the three characters following "!" Are extracted. The conversion rule is determined by using the name with ".LOD" as the name of the file in which the user program is stored. However, the conversion rule can be given to the user to give the conversion rule a degree of freedom. For example, the pattern of the conversion rule is designated by a regular expression or a mask pattern. A regular expression for selecting the target to start the user program from the name of the transfer target file, and a mask pattern for extracting the character (string) used for the name of the file storing the user program from the name of the transfer target file, It is a method that allows the user to specify a regular expression for obtaining the name of the file in which the user program is stored using the extracted character (string).

[0016]

Since the present invention has the above-mentioned method,
It is not necessary to register in advance the name of the file to be transferred (start condition) and the name of the user program to be started (start information) corresponding to it, and the operation becomes simple. Further, since the means for registering the activation condition and the activation information is unnecessary, the structure becomes simple.
