Abstract

PURPOSE:To save selectively a source program and an object program by the command and to execute easily the program correction by storing the source program and the object program onto the same memory. CONSTITUTION:When a source program SP is recorded in a magnetic disk 5, a SAVE command is used. When an object program (ObjP) is recorded in a magnetic disk 5, a GENERATE command is used. When an SP is recorded in the magnetic disk 5, the SP is read from a magnetic disk 5 by a command LOAD and by a compiler 1, translated and executed, the correction change of the SP is easily executed. When the ObjP is recorded to the magnetic disk 5, the execution is directly executed by the ObjP. Consequently, the program can not be corrected and changed, and the processing time is short.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a computer programming execution method.

[Summary of the invention]

This invention is a computer programming execution method in which a source program and an object program are stored in the same memory, and by selectively saving them to a magnetic storage means, it is possible to save programs according to the purpose. .

[Conventional technology]

Programming processing methods include an interpreter method and a compiler method. The interpreter method interprets a source program written in a high-level language such as RAS I C line by line and executes it sequentially. This method is suitable for applications that require interactive functionality.In the interpreted method, if there is a programming error, the erroneous line number and error code will be displayed during execution, and execution will be aborted. If you correct the error part interactively, you can run it again.

However, - time is required for line-by-line interpretation, and processing time is long.

In the compiler method, a source program is translated into an executable object program in machine language, and then executed by this object program.9 For example, a source program is created on a disk using a text editor, and this source program is translated using a compiler. Convert runtime routines into relocatable object programs.

This relocatable object program is combined and edited by a linker to generate an executable object program, and is executed by this executable object program.

Since the compiler method directly executes a machine language object program, the processing speed is fast. However, the compiler method, for example,
As shown in the above publication, in the compiler system, where it is difficult to provide an interactive function, if there is a programming error, the compiler and linker will display all the errors and the program will not be executed.

[Problem that the invention seeks to solve]

In the ink printer type, a program written in a high-level language is executed while being interpreted sequentially, so it cannot be expected to improve processing speed. In the compiler system, once a program is recorded on a disk as an object program, it is no longer possible to deal with the source block (this makes it difficult to modify the program).

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a computer programming execution method that is fast in execution speed and allows programs to be easily modified.

When recording multiple programs on one disc, even if each program has a shared routine, recording all the individual programs is inefficient.

Therefore, another object of the present invention is to provide a computer programming execution method that is efficient in program recording.

(Means for solving the problem) The present invention compiles a source program written in a high-level language into an object program written in machine language for each predetermined unit, and combines the source program and the compiled object program into a common program. store in memory,
A computer programming execution method in which variables and information regarding the variables are stored in a variable-related area provided in memory, and an object program and variables are combined and executed, and the source program and the object program are selected by a command. This is a computer programming execution method characterized in that the data is saved in a magnetic storage means.

[Effect]

A source program and an object program are stored in the same memory, and the source program and object program are selectively saved by a command. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a compiler, 2 is a keyboard, 3 is a CRT display, and 4 is a memory □.

The compiler 1 is an incremental type compiler that sequentially compiles a predetermined unit, for example, one line of a source program.

The compiler 1 has not only a compiling function but also an editing function. Compiler 1 and Memo I74 are
It is connected in both directions.

A source program is given to the compiler 1 from the keyboard 2. For example, the language of the source program is B.
ASIC is used. The input source program is sequentially compiled into an object program by a compiler 1. The source programs are sequentially stored in a memory area 4A on the memory 4. The compiled object programs are edited in the order of execution and sequentially stored in the memory area 4B on the memory 4.

A memory area 4C is provided on the memory 4 for forming a symbol table of variables and information regarding the variables. Information recorded in the symbol table regarding variables includes the line number where the variable is used, the type of the variable (integer, real number, double-precision real number, or character array), the number of dimensions and number of elements in the case of an array, Address reference number, etc. within the value of the variable.

As for part representation, binary representation is used for numerical values.

Modifications and changes to programs can be made interactively.

That is, when a part of the source program is changed, the changed source program is retranslated by the compiler 1, and the object program is rewritten. Therefore, the object program can be modified without modifying the entire source program.

During execution, variables are linked based on information about variables in the variable symbol table, and execution is performed by the object program.

Since the execution is performed by the object program stored in the memory area 4B, the processing speed is faster than the interpreter method.

The source program and object program are stored on a common memory 4. Therefore, as shown in FIG. 2, the source program and the object program can be selectively recorded on the magnetic disk 5.

When recording the source program on the magnetic disk 5, the "5AVE" command is used.

When the '5AVE' command is given, the source program recorded in the memory 4 is recorded on the magnetic disk 5.

When recording an object program on the magnetic disk 5, a "GENERATE" command is used.

When the "GENERATE" command is given, the object program recorded in the memory 4 is recorded on the magnetic disk 5.

When a source program is recorded on the magnetic disk 5, the source program is read out from the magnetic disk 5 by the command "LOAD", translated into an object program by the compiler 1, and executed. In this case,
It is easy to modify and change the source program.

When an object program is recorded on the magnetic disk 5, execution is performed directly by this object program. Therefore, in this case, modifying the program,
Although changes cannot be made, the processing time is short. Also,
For example, when selling a program, if it is recorded as an object program in this way, it cannot be easily copied.The user can selectively record the source program and the object program on the magnetic disk 5 according to the purpose of the program. do.

When storing an object program using the ``GENERATE'' command, you can choose whether to include runtime routines or not include runtime routines.Since runtime routines can be used in common, multiple programs can be stored on one disk. If you save a program by including a runtime routine in each program, the disk will not be used efficiently.In such a case, if one program on the disk is recorded including a runtime routine, , other programs can be recorded without including runtime routines.

Although BASIC is used as the programming language in this embodiment, other languages such as FORTRAN and PASCAL can be used in the same manner.

〔Effect of the invention〕

According to this invention, a source program and an object program are stored on a common memory. Therefore,
Source programs and object programs can be selectively saved using commands. Therefore, programs that are easy to modify and programs that execute quickly can be selectively saved depending on the purpose. Also, you can save without including runtime routines, so
Disc recording efficiency is good.
