Understanding COBOL
Before exploring Murach's approach to COBOL, it's essential to grasp the fundamentals of the language itself.
What is COBOL?
COBOL is a high-level programming language that was developed for business use. Its syntax is designed to be readable and understandable, which allows for clear communication of business logic. Key characteristics of COBOL include:
- English-like Syntax: COBOL code resembles English sentences, making it easier for non-programmers to understand.
- Data Processing Capability: It is particularly adept at processing large volumes of data and performing calculations.
- Business Focus: Originally designed for business applications, COBOL is ideal for tasks such as payroll processing, banking transactions, and inventory management.
History and Evolution of COBOL
COBOL has undergone several iterations since its inception:
1. 1960s: The first version of COBOL was developed, focusing on data processing for businesses.
2. 1970s: The language evolved with the introduction of structured programming concepts.
3. 1980s: Object-oriented features were introduced, allowing for more complex programming paradigms.
4. 2000s: COBOL 2002 introduced XML support and other modern programming features.
Despite technological advancements, COBOL remains relevant due to its widespread use in legacy systems.
