The calculation control unit 11 is a part that interprets the content of the e-mail transmitted from the user terminal 80 at a remote place, and performs processing according to the content.

The first memory 13 stores the name of a calculation program stored by the remote computer 10 and started by the above-mentioned request by e-mail, and the corresponding keyword. FIG. 2 is a diagram illustrating an example of the internal configuration of the first memory 13. In the keyword area and the program name area in the figure, the name of the calculation program and the keyword corresponding thereto are stored, respectively. Note that the calculation program itself is stored in the first memory 13 or another location in the remote calculation processing device 10.

The second memory 14 stores the contents of the electronic mail, input data for executing the calculation program, output data of the calculation result, and error information generated during the execution of the processing. As the contents of the e-mail, a sender address, a copy sender address, a subject, a body, an attached file, and the like are stored. The communication unit 12 controls communication between the remote calculation processing device 10 and the mail server 20. Specifically, the communication control unit 11 requests the calculation control unit 11 to confirm receipt of a mail, take out a mail, or send a mail. For example, to the mail server 20 via the network 30.

Next, the flow of the processing of the remote calculation processing device 10 performed based on the calculation control means 11 will be described. FIG. 3 is a diagram showing the processing flow. First, a remote user who wants to use the calculation program stored in the remote calculation processing device 10 transmits a use request from the user terminal 80 by e-mail.

Is a file of the input data used in the calculation program. The transmitted e-mail is stored in the mail server 20.

The calculation control means 11 of the remote computer 10 accesses the mail server 20 periodically via the communication means 12 and the network 30, and the e-mail is sent to the mail address for the remote computer 10. Check if it has arrived. If the e-mail has arrived, one of the first-arrived e-mails is taken out, the contents of the e-mail are stored in the memory inside the calculation control means 11, and this e-mail is deleted from the mail server 20 (step S in FIG. 3).
1). If the e-mail has not arrived, the operation is paused for a predetermined time and then the processing is repeated from the access to the mail server 20 again.

Next, the calculation control means 11 interprets the contents of the mail stored in its own internal memory, and extracts data such as a sender address, a copy sender address, a subject, a text, and an attached file therefrom. It is stored in a predetermined area of the second memory 14 (step S2 in FIG. 3).

Next, the calculation control means 11 stores the subject of the mail stored in the second memory 14, that is, the keyword of the calculation program required to be processed, in the first memory 13.
(See Fig. 3)
Step S3). If the subject does not match any of the keywords described in the first memory 13, error information to that effect is stored in a predetermined area of the second memory 14, and a reply mail generation step (FIG. The process proceeds to step S6) of 3.

When a matching keyword is found, the calculation control means 11 stores the attached file stored in the second memory 14, ie, the input data for the calculation sent by e-mail, in the second The data is copied to the input data area of the memory 14 (step S4 in FIG. 3). If the attached file does not exist, error information to that effect is stored in a predetermined area of the second memory 14, and the process proceeds to a reply mail generation step (step S6 in FIG. 3) described later.

When the input data is copied, the calculation control means 11 recognizes the calculation program corresponding to the searched keyword from the program name described in the first memory 13 and starts the calculation program. When the calculation program starts, the input data copied to the input data area of the second memory 14 is read based on the calculation program, and a predetermined calculation process is executed. The result of the calculation is output to the output result area of the second memory 14 and stored (step S5 in FIG. 3). If the calculation program terminates abnormally for some reason, error information to that effect is stored in a predetermined area of the second memory 14.

When the calculation by the calculation program is completed as described above, the calculation control means 11 sends the request source of this calculation processing to
That is, a reply mail to the user who transmitted the e-mail from the remote user terminal 80 is created (step S in FIG. 3).
