GUI and Object Oriented Programming in COBOL
Alden C. Lorents · 1997
Various schools are struggling with the introduction of Object Oriented (00) programming concepts and GUI (graphical user interfaces) within the traditional COBOL sequence. 00 programming has been introduced in some of the curricula with languages such as C++, Smalltalk, and Java. Introducing 00 programming into a typical COBOL sequence presents some interesting challenges. There are a number of new concepts to introduce along with various design issues that are relatively new to 00 program design, such as file maintenance and data objects. Most C++ programming courses tend to work with objects that are more user interface related, such as traditional GUI objects. This paper describes an example of using 00 COBOL and Dialog Systems (GUI builder) in an advanced programming applications course.
