OL2A: Basic CL Programming Workshop for IBM i
DURATION: 2 days
SCHEDULED DATES: TBD – Contact Us for more Information
PURPOSE
This classroom course is designed to teach the students to write control language (CL) programs which may be used to perform a variety of system and application control functions. The students are taught to write basic and intermediate level, interactive programs.
AUDIENCE
This course is intended for application programmers, system programmers, and others who have a need to write control language programs.
PREREQUISITES
Before taking this course, the student should be able to:
• Write simple programs in another programming language
• Perform basic IBM i operations
• Code the commands necessary to send inquiry and information messages
• Use data description specifications (DDS) and the Rational Development Studio (WDS) tools (Programming Development Manager (PDM) and source entry utility (SEU)) to create physical, logical, and display files
• Use the WDS or RDP tools to enter CL source statements and create CL programs
• Describe basic work management
• Create a library, output queue, and a job description
These prerequisites can be met through successful completion of the following courses:
• Introduction to IBM i for New Users (OV98)
• IBM i Application Programming Facilities Workshop (OL49 or OV49)
OBJECTIVES
After completing this course, you should be able to:
• Create CL programs that incorporate the full range of language operations and functions:
– Arithmetic, string, and boolean expressions
– Relational operations
– Built-in functions
– File handling
– Retrieving IBM i information
– Program interaction and parameter passing
• Use the interactive source debugging facilities of STRDBG
• Describe how to create and call Integrated Language Environment (ILE) modules, programs, and service programs
• State the purpose of the parameters on the CRTBNDCL command and each section of the control language compiler listing
