Abstract

PURPOSE:To connect the systems by a non-transparent mode line so that a target program can be transferred by decomposing the target program into constitution data, converting it in accordance with conversion rule information and transmitting it, bringing received data to reverse conversion to reproduce the target program, and storing this target program. CONSTITUTION:A conversion processing means 12 divides a target program into one digit each of hexadecimal data from a transmitting side storage means 11, and there after, converts it in accordance with conversion rule information stored in a conversion rule table 13 and delivers it to a transmitting means 14. The transmitting means 14 transmits the delivered data by using a communication line 3 of a non-transparent mode procedure. A receiving side computer system 2 receives this data by a receiving means 24, a reverse conversion processing means 22 returns it to the original target program in accordance with reverse conversion rule information stored in a reverse conversion rule table 23, and a receiving side storage means 21 stores the delivered target program. The operation is repeated until the data obtained by dividing the target program into units of one digit of a hexadecimal number is gone. In such a way, the target program can be transferred easily in a short time by using a non- transparent mode line.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for transferring an object program between computer systems via a communication line in order to mutually use the object program between a plurality of computer systems. .

[Conventional technology]

Currently, each computer system's central processing unit, main memory,
In order to effectively utilize limited resources such as arithmetic processing units, input/output devices, peripheral processing units, and data, measures are taken to connect each computer system with communication lines and share these resources. .

In this case, since the communication means is simple, computer systems are often connected using a non-transparent line with a code string that cannot be transmitted without transparency.

Some data in the target program is assigned as a control character and cannot be communicated on a non-transparent mode line, such as "02J" (data in hexadecimal representation), which indicates the beginning of text in a non-transparent mode procedure, or similar. Because the line contains [03J (data expressed in hexadecimal), which indicates the end of text, the target program cannot be transferred using this line.

Therefore, when using a target program, the system containing the target program is saved onto a magnetic tape, transported by some means of transportation to the system or location where the target program is to be used, and then transferred to a magnetic tape device. The method used was to load the tape and store it in the user's computer system.

[Invention or problem to be solved]

The above-mentioned conventional target program diversion method has the disadvantage that the farther the distance between computer systems, the more effort, time, and expense required for transportation.

Further, since the medium is a magnetic tape, there is a drawback that the operator has to load the magnetic tape into a magnetic tape device, which is a troublesome task.

An object of the present invention is to solve these problems and to provide a computer system that can easily and quickly transfer target programs between computer systems in remote locations using a non-transparent mode line without operator intervention. The purpose is to provide a program transfer method between

[Means to solve the problem]

The sending side computer system 1 is composed of a sending side storage means 11, a conversion processing means 1.2, a conversion rule table 13, and a sending means 14. On the other hand, the receiving side computer system 2 includes a receiving side storage means 2], an inverse transformation processing means 22, an inverse transformation rule rule 23, and a receiving means 24.

The sending side storage means 11 stores the target program of the sending side computer system 1, and is composed of, for example, a magnetic disk device, a main storage device, etc.

In addition, the conversion rule table 13 contains 16 types of hexadecimal data 1
A storage means that stores conversion rule information for converting digits into two digits of 16 types of hexadecimal data that can be communicated over a non-transparent mode line, for example conversion rule information as shown in FIG.

Note that the converted data shown in FIG. 2 may be any other data as long as it is two-digit hexadecimal data that can be communicated over a non-transparent mode line.

On the other hand, the inverse conversion rule table 23 is the conversion rule table 1
A storage means that stores inverse transformation rule information for returning the converted data converted in step 3 to the original data, which is the to-be-converted data. Information is memorized. However, the inversely transformed data in FIG. 3 and the transformed data in FIG. 2 may be other inversely transformed data as long as they have the same value.

Note that in FIG. 1, the communication line 3 is a non-transparent mode line.

Next, the operation of this embodiment having the above configuration and functions will be explained with reference to FIG. 4.

First, a target program is stored in the sending side storage means 11.

Step 102)
, if the target program still exists, convert it into data that can be communicated over the non-transparent mode line according to the conversion rule information stored in the conversion rule file 13 (step 103).
, and pass it to the transmitting means 14. transmission means]. 4 transmits the passed data from the transmitting side computer system 1 to the receiving side computer system 2 using the communication line 3 of the non-transparent mote procedure (step 04).

The receiving side computer system 2 receives the data sent using the communication line 3 using the receiving means 24],
