:bt top-level command

$Revision: 5.0.2.2 $

No arguments.

The :bt command provides a quick way to scan the stack (contrast with :zoom). :bt has no abbreviation.

Here is the effect of the :bt command on the example above (attempt to evaluate foo which has no value). In this case, :zoom is printing all frames (:all t) so :bt does as well.

[1] USER(24): :bt
Evaluation stack:

EVAL <-
TPL::READ-EVAL-PRINT-ONE-COMMAND <-
EXCL::READ-EVAL-PRINT-LOOP <-
TPL::TOP-LEVEL-READ-EVAL-PRINT-LOOP1 <-
TPL:TOP-LEVEL-READ-EVAL-PRINT-LOOP <- APPLY <-
TPL:START-INTERACTIVE-TOP-LEVEL <- TPL::START-TOP-LEVEL <-
EXCL::START-REBORN-LISP
