RCB (Run Control Block)

For each session that runs a program, the RCB (Run Control Block) keeps track of the processing occurring for the executing application. The run control block contains:

• Current position in the application:
  • Procedure block
  • Current instruction (t-code)
  • Compilation release
• Executor work areas
• Updateable code pointers
• A list of all programs and panels that were accessed in the current execution of the application
