To View the Current Trace Stack (Visual LISP IDE)

The trace stack can be used when debugging a program.

1. In the Visual LISP text editor, set a breakpoint or suspend the execution of your AutoLISP program.
2. Click View Trace Stack.
3. In the Trace Stack window, double-click the element or frame you want to inspect.
   

   The Trace Stack window displayed shows a function call frame for the stack-tracing function. The second element, or frame, in the trace stack is highlighted:

   [2] (STACK-TRACING 10 10)

   The number [2] simply identifies it as the second element in the stack. The numbers following the stack-tracing function name (10 10) indicate the actual values that were passed to the function.
