Figure A-3. The user has called Proc1 in PTZTest14 from the Cedar interpreter in the User Executive viewer. Breakpoint 1 was reached, and the user clicked the Show Stack/Top Frame command to get a description of the current execution location in the User Executive viewer. It shows that execution is inside Tail, which was called from TestInlineProcedure, which was called from Proc1. The source location numbers are character positions (numbered from the start of the file). The user can access the local variables for Tail, TestInlineProcedure, and Proc1 directly. [Recall that Navigator does not provide expected behavior for displaying the values of variables.]
