This course introduces and explains the PL/I programming language, and teaches experienced programmers how to code, maintain and debug PL/I programs. As well as covering the syntax of all the main PL/I statements, the course gives attendees a great start to using PL/I confidently, correctly and efficiently. Several exercises are used to consolidate all the major topics covered. The final exercise builds up to a complete and well structured program. The course is designed for the IBM Enterprise PL/I compiler.<br><br>This course is available 'on demand' (minimum 2 students) for public presentations and for one-company, on-site presentations.
