Objective

• 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
  • Message 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
• Create user-defined commands with and without parameters
• Create a control language program that processes a database file
• Create and invoke a program that is activated periodically and executes asynchronously from other jobs
• State the purpose of the parameters on the CRTBNDCL command and each section of the control language compiler listing
