During a debugging session, the Debugger allows you to start and stop procedure execution as you want, and even execute procedures that are not part of your application. All procedures the Debugger executes are added to the procedure call stack. The procedure call stack is a last-in-first-out (LIFO) memory structure that keeps track of the execution status of each procedure as it calls a subprocedure or invokes a trigger block.

The following sections cover:

• Open and incremental execution
• Procedure interruption
• Procedure termination
