About COBOL & COBOL Tutoring

COBOL, an acronym for Common Business-Oriented Language, is a high-level programming language designed for business applications. It emerged in the late 1950s and was primarily aimed at the business, finance, and administrative systems for companies and governments. COBOL is known for its simplicity, which comes from its English-like syntax that makes it readable for non-programmers, yet powerful enough to handle the massive data processing operations of large enterprises.

The language exists in various versions, with COBOL-85 being one of the most widely accepted standards alongside more modern iterations, such as Object-Oriented COBOL. Related entities to COBOL include:

  • American National Standards Institute (ANSI): Responsible for standardizing the versions of COBOL.
  • Integrated Development Environment (IDE): Tools like Micro Focus Visual COBOL or IBM's RDz (Rational Developer for z) which are used to write, debug, and maintain COBOL programs.
  • Mainframe computers: Large-scale computing systems where COBOL applications are commonly run.
  • Database systems: COBOL often interacts with databases like DB2, IMS, or Oracle, managing important business data.

When tutoring someone who struggles with COBOL, the best strategy involves a hands-on approach coupled with real-world examples. Beginners should be encouraged to read COBOL code to become familiar with its syntax and style. Starting with simple programs that manipulate numeric and character data is beneficial before moving onto more complex concepts like file handling and database interaction. Pairing learners with an experienced mentor can also prove invaluable, as they can provide instant feedback and clarification.

Common concepts in COBOL include:

  • Data Division: This is where all variables are defined, resembling a complex data structure.
  • Procedure Division: The set of instructions telling the program what to do with the data.
  • Sequential and Random file processing: Vital for business applications that handle large volumes of data.

Among the most challenging concepts for newcomers to COBOL tend to be:

  • The extensive use of divisions and sections which can be daunting to understand in terms of program structure and flow.
  • The very detailed data description and level numbering system, which requires a precise understanding of how data is stored and accessed.
  • Understanding the intricacies of legacy code that has been patched and evolved over multiple decades, often with a lack of up-to-date documentation.

To conclude, COBOL's longevity is a testament to its efficiency in business environments. The key to mastering it is to understand its structured nature and to gain hands-on experience with real business-oriented programs.
