TUWELQuinn ECTS survey


  • Semester hours: 2.0
  • Credits: 3.0
  • Type: VU Lecture and Exercise
  • Format: Presence

Learning outcomes

After successful completion of the course, students are able to 

  • setup a development infrastructure to do programming and maintenance work in the PL/I programming language
  • understand and apply the basic programming concepts of the PL/I language and its environment
  • create new and modify existing PL/I programs and execute these programs in a provided environment

Subject of course

The course provides a theoretical and practical introduction to software development in the PL/I programming language. Students learn the language specific constructs.

During the course there are different exercises to solve, e.g.:

  • Set up a mainframe development environment to write, build and run your first PL/I or COBOL program
  • Develop a batch program to process file based data input (data sets)
  • Develop an advanced batch program that uses a mainframe data store



Teaching methods

In several lectures, students are taught theoretical basics, methods and concepts of the PL/I programming language. In parallel the students are required to solve three practical exercises to apply the theoretical skills provided in the lectures. The evaluation interviews will enable the students to obtain feedback on their work.
