Method and system for converting traditional program language into modern program language

Abstract

The invention relates to a method and a system for converting a traditional program language into a modern program language. The method comprises the following steps that: obtaining a COBOL (Common Business-Oriented Language) source code which needs to be converted and a corresponding configuration rule; generating the COBOL source code into a corresponding JAVA source code according to the corresponding configuration rule; and configuring a basic environment for the JAVA source code. By use of the method, a configuration file is loaded, the COBOL source code which needs to be converted is converted into the JAVA source code, an SDK (Software Development Kit) is used by aiming at the converted JAVA source code to carry out data type packaging and the basic environment configuration of a method interface, a basic platform is adopted to carry out online transaction processing, COBOL grammar conversion is comprehensively supported, program language accuracy before conversion is kept, theredirecting and the pointer assignment processing of the COOL are truly realized, practical operation efficiency is high after conversion, maintainability is good, and maintenance cost can be lowered.

Description

Technical field [0001] The present invention relates to a programming language conversion method, and more specifically to a method and system for converting traditional programming language to modern programming language. Background technique [0002] The conversion of traditional programming languages ​​to modern high-level programming languages ​​has always been an important research direction in the field of computer compilation. [0003] As a process-oriented computer high-level programming language specially designed for business data processing, COBOL has a history of nearly 50 years since its birth. It is still widely used in very important business data processing fields such as banking, securities and manufacturing industries. According to incomplete statistics, 492 of the global top 500 companies (including all the top 100 companies) use COBOL language. The current investment in COBOL has exceeded US$3 trillion, and the programs written in COBOL have exceeded 200 billion...

[0003] As a process-oriented computer high-level programming language specially designed for commercial data processing, COBOL has a history of more than 50 years since its birth, and is still widely used in very important commercial data processing fields such as banking, securities and manufacturing industries. According to incomplete statistics, 492 of the world's top 500 companies (including all the top 100) have used the COBOL language. At present, the investment in COBOL has exceeded 3 trillion US dollars, and the programs written in COBOL have exceeded 200 billion lines. Currently, the COBOL language The developed system has the following limitations: First, due to the current development of the Internet, daily transaction data processing has multiplied, and the system developed by traditional COBOL has been difficult to meet the business data processing requirements, but because the COBOL language is relatively old, it is difficult to The increase in future business volume is supported through cluster technology; second, because COBOL, as a traditional programming language, has many limitations, there are relatively few programmers who use and learn COBOL, which leads to an increase in the maintenance pressure of the existing huge COBOL system, and it is difficult to implement it in the current There is a system for development to meet the development of business needs; thir
