Finding the Location of the Syntax Error in Your Program
Using the Visual LISP Environment
Introducing Visual LISP Debugging Features
To debug a program, you can trace execution, trace the values of variables during execution, and view the sequence in which expressions are evaluated.
Programs do not always behave in the way they were intended. When the results you get appear to be wrong, or cause the program to fail, it can be difficult to determine what is going wrong. Visual LISP® provides many features that help you with the debugging process—finding and resolving program problems.
