3.2 Entering and exiting the Debugger

3.2.4 Exiting the Debugger

You leave the Debugger and return to the top level whenever you complete the evaluation that invoked the Debugger. You can also explicitly exit the Debugger without completing an evaluation by selecting one of the following options:

Select the option to return to the top level of Lisp. The options list always contains such an option, which is often invoked by the command:a.
Type the command:a:t, which aborts the current evaluation and returns you to the Lisp top level, even if you are in a recursive Debugger level. You can use this command any time you are at the Debugger prompt, even if the command is not shown in the list of current options.

The following example shows the effect of using:a to return to the top level:

> test
>>Error: The symbol TEST has no global value.
SYMBOL-VALUE:
   Required arg 0 (S): TEST
:C  0: Try evaluating TEST again
:A  1: Abort to Lisp Top Level
-> :a
Abort to Lisp Top Level
Back to Lisp Top Level
>

Once you are back at the top level, the Lisp prompt appears and you can continue entering expressions to be evaluated.
