| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
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 error when an attempt is made to evaluate
foo
which has no value. When the error occured, :zoom is printing all frames (:all
t
) so :bt does as well.
USER(23): foo Error: Attempt to take the value of the unbound variable `FOO'. [condition type: UNBOUND-VARIABLE] [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
See top-level.htm for more information on top-level commands.
