*zoom-display*

The value of this variable is the maximum number of stack frames displayed by the :zoom command unless a value is specified for the count argument to :zoom. If a value is specified for count, this variable is set to that value. This value should be a positive integer or t (but not another true value and not nil). An integer specifies the number of frames. t specifies that all applicable frames should be printed.

This variable is not available in Lisp images built with a minimal top level, that is built with the include-tpl argument to build-lisp-image specified nil. See Minimal top levels in building-images.htm for information on minimal top levels.

See debugging.htm for more information on the debugger.
