Abstract

PURPOSE:To attain the free delivery of a symbol variable value between a program and a command procedure by declairing a temporary symbol variable and executing the delivery of the specified symbol variable value between the program and command procedure. CONSTITUTION:The temporary symbol variable, which is declaired by a temporary symbol variable declairing part 11 of a program 10, is registered as the symbol variable by a temporary symbol variable registering part 31 of a command procedure 30. A symbol variable referring and setting part 32 of the command procedure 30 refers the temporary symbol variable as this registered symbol variable and sets a value. A temporary symbol variable value returning part 33 of the command procedure 30 designates the type of the temporary symbol variable, whose value is returned to the program 10, and processes the value so as to be delivered from a symbol variable area 40 to a temporary symbol variable area 20. Thus, a temporary symbol variable value referring part 13 of the program 10 can refer the value of the temporary symbol variable which is processed by the command procedure.

[Industrial application field]

The present invention relates to a symbolic variable processing method that allows symbolic variable values to be exchanged between a program and a command procedure.

A command procedure consists of a series of registered command strings, and is called from a program to execute the function of the command string. Symbolic variables are
A variable specific to this command procedure. In a program that uses such a command procedure, it is necessary to read the symbolic variable value of the command procedure, so it is necessary to configure the program so that this successive processing can be performed freely from the program side.

[Prior Art] Conventionally, the symbolic variable value of a command procedure was passed to a program by the command procedure calling the program. In other words, since a symbolic variable is a variable unique to a command procedure, the command procedure first calls a program with an initiative, and then the program called in this way executes the process of referencing the symbolic variable value. It was being processed.

[Problem that the invention seeks to solve]

Due to this configuration, the prior art has a problem in that a program that is not called from the command procedure cannot read the symbolic variable values of the command procedure. Therefore, the program could not freely refer to the values of the symbolic variables of the command procedure. Such limitations make it impossible to improve program productivity and performance.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a symbolic variable processing method that can realize the free exchange of symbolic variable values between a program and a command procedure.

[! Means to solve one problem] FIG. 1 is a diagram showing the principle configuration of the present invention.

The program 10 includes a temporary symbolic variable declaration section 11, a temporary symbolic variable value setting section 12, and a temporary symbolic variable value reference section 13. This temporary symbolic variable declaration section II processes to declare a temporary symbolic variable, and also uses the temporary symbolic variable area 20.
The temporary symbol variable value setting unit 12 performs processing to set
The value of the temporary symbolic variable that will be passed to the command procedure 30 is set in the set temporary symbolic variable area 20, and the temporary symbolic variable value reference unit 13 sets the value of the temporary symbolic variable that will be returned from the command procedure 30. The value of the symbolic variable,
Processing is performed so that it is referenced via the set temporary symbol variable area 20.

On the other hand, the command procedure 30 includes a temporary symbolic variable registration section 31, a symbolic variable reference setting section 32, and a temporary symbolic variable value return section 33. This temporary symbol variable registration unit 31 is
By storing the temporary symbolic variable information set in the temporary symbolic variable area 20 in the symbolic variable area 40, the temporary symbolic variable declaration section 1
1, the symbolic variable reference setting section 32 performs processing to refer to and set the symbolic variable in the symbolic variable area 40, and the hour symbol variable value return section 33 performs the following steps: Processing is performed so that the value of the temporary symbolic variable, which is the processing result for the registered symbolic variable, is passed from the symbolic variable area 40 to the temporary symbolic variable area 20.

[Effect]

In the present invention, the temporary symbol variable declaration section 11 of the program 10
The temporary symbolic variable declared by is registered as a symbolic variable by the temporary symbolic variable information section 31 of the command procedure 30. The symbolic variable reference setting unit 32 of the command procedure 30 refers to the temporary symbolic variable as a registered symbolic variable according to the execution of the command string,
Set the values. Then, the temporary symbolic variable value return unit 33 of the command procedure 30 specifies the type of temporary symbolic variable whose value is to be returned to the program 10, and passes the value from the symbolic variable area 40 to the temporary symbolic variable area 20. Process as follows. This allows the temporary symbolic variable value reference unit 13 of the program 10 to refer to the value of the temporary symbolic variable processed by the command procedure 30.

In this way, according to the present invention, the program 10 can read the value of a symbolic variable without being called by the command procedure 30. At this time, the type of symbolic variable to be passed to the program 10 is specified by the command procedure 30.
can now be specified. Moreover, in the present invention, the program 0 called from the command procedure 30 is
The conventional technology that refers to the value of a symbolic variable can be retained as is.

Therefore, symbolic variable values can be exchanged freely between the program 10 and the command procedure 30.

〔Example] Hereinafter, the present invention will be explained in detail according to examples.

FIG. 2 shows a configuration diagram of an embodiment of the present invention. In the figure, 10a is a first program which is an application program, tab is a second program which is also an application program, 20.
30 and 40 respectively represent a temporary symbol variable area, a command procedure, and a symbol variable area, as in FIG. In addition, in the figure, the first program 10a is referred to as "PROCI".
'', the second program 10b may be expressed as ``'PROC;2'', and the command procedure 30 may be expressed as ``PROCI''''. As shown in this figure, one or more programs 10 will call a command procedure 30 to utilize the functions that the command procedure 30 performs.

Next, the symbolic variable processing method of the present invention will be explained according to the processing procedure executed by the present invention.

The first program 10a that needs to read the symbolic variable value of the command procedure 30 first enters the declaration process of a temporary symbolic variable, as shown by ■ in the figure. Here, the temporary symbolic variable is the command procedure 30
It can be said that it is a pseudo symbolic variable introduced to read the symbolic variable value of ” consists of the same.

As a result of this temporary symbolic variable declaration processing, the temporary symbolic variable area 20 is set on, for example, the DASD, as shown by ■°. Next, the first program lOa executes a process of setting a temporary symbolic variable value, as shown by ■, and sets a value in the set temporary symbolic variable area 20, as shown by ■゛. . In this way, the preparation for passing the area and value of the temporary symbol variable to the command procedure 30 is completed. Then, the command procedure 30 is called.

When called from the first program 10a in this way, the command procedure 30 first registers the temporary symbolic variable declared in the first program 10a as a symbolic variable, as shown by ■ in the figure. registration process will be performed. Through this registration process, the temporary symbolic variable information stored in the temporary symbolic variable area 20 is moved to the symbolic variable area 40, as shown by
In the command procedure 30, temporary symbolic variables can be treated in the same manner as symbolic variables. That is, as a result of this registration process, the command procedure 30 will, from now on, store temporary symbolic variables registered as symbolic variables via the symbolic variable area 40, as shown by Reference processing and setting processing can be performed freely.

In this way, when the command procedure 30 executes processing and needs to return the values of necessary temporary symbolic variables registered as symbolic variables to the first program 10a, the command procedure 30 executes the process. , as shown by ■ in the figure, value return processing is performed.

This value return process is performed in the symbolic variable area 4, as shown by ■°.
The symbolic variable value information related to the temporary symbolic variable stored in the temporary symbolic variable J! ! It will be executed by moving to 20. By executing this process, control of program execution returns to the first program tOa, and the
The program 10a continues processing by referring to the returned value of the temporary symbol variable.

By the procedure described so far, the first program l
oa can refer to the symbolic variable values of the command procedure 30 even if it is not called from the command procedure 30. Then, the command procedure 30
The symbolic variable value information related to the temporary symbolic variable to be returned to the program 10a can be selected at any time from among those registered as symbolic variables.

The processes indicated by ■ and ■° in the figure are executed by the command procedure 30.
This represents a procedure in which when the second program 10b calls the second program tab, the called second program 10b refers to the symbolic variable value of the command procedure 30 by referring to the symbolic variable area 40. This procedure is prior art. In this way, even if the present invention is implemented, the symbolic variable processing method of the prior art can be used as is without any harm.

Further, the procedures indicated by ■ and ■'' in the figure represent procedures in which the second program 10b executes a temporary symbolic variable declaration process and sets a temporary symbolic variable value in the temporary symbolic variable area 20. In this way, in the symbolic variable processing method of the present invention,
When there are multiple application programs, each application program can freely declare a temporary symbolic variable and read the symbolic variable value related to the temporary symbolic variable from the command procedure 30.

Although the illustrated embodiments have been described above, the present invention is not limited thereto. For example, the number of application programs is not limited to two, and the number of command procedures is not limited to one.

[Effects of the Invention] According to the present invention, a program can read the value of a symbolic variable of a command procedure without being called from the command procedure. At this time, the command procedure can specify the type of symbolic variable that will be passed to the program. Furthermore, in the present invention, a program called from a command procedure can refer to the values of symbolic variables as before. Therefore, symbolic variable values can be freely exchanged between programs and command procedures, and symbolic variable values can also be freely exchanged between programs via command procedures. From now on, it will be possible to improve program productivity and performance.
