In this lesson, you

• Learned about local and global variables.
• Set and removed breakpoints in a program.
• Stepped through a program while it was executing.
• Watched and dynamically changed the value of program variables during execution.
• Saw how local variables are reset to nil after the function that defined them completes its run.

The tools you learned in this lesson will be part of your daily work if you intend to develop AutoLISP applications with VLISP.
