To be successful with the IBM i operating system, you'll need to be fluent in Control Language (CL). This lab workshop covers CL from start to finish. The "Control Language Programming" workshop introduces Control Language and helps you understand its primal position in the IBM i world, including its role in the Integrated Language Environment (ILE).
Recommended Schedule: 5 day lab workshop
Who Should Attend This class is appropriate for programmers who will be writing Control Language programs to direct processes on the server.
Prerequisites A working knowledge of AS/400 user interface, operations, and programming tools is required. Previous programming experience on another hardware platform may be helpful.
For those programmers new to IBM i, the combined "IBM i Concepts and Control Language Programming" workshop may be more appropriate.
What You Will Accomplish At the end of the course, students will be able to:
Enter Control Language commands into the system
Use the CL prompt facilitity
Compile CL programs
Define and process variables in a CL program
Use CL’s program control structures
Call programs and pass parameters to them
Handle errors which may occur during the running of a CL program
Use CL to process data files and displays
Process system information from data areas and system values
Create customized user-defined commands
Understand CL’s role in the Integrated Language Environment (ILE)
What You Will Receive Each student receives:
Custom printed handout, containing class notes
Completion certificate
