*exit-on-eof*

When the top-level read-eval-print loop reads an EOF (end of file, simulated by Control-D on some systems), the action of Allegro CL depends on the value of this variable. If *exit-on-eof* is t, Lisp will exit. If it is nil (which is the default), the user will be asked if he really wants to exit Lisp. If it is a positive integer, Lisp will exit after exactly that number of consecutive EOFs. Any value other than nil or a positive integer is equivalent to the value t. EOF calls exit with no arguments.

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 top-level.htm for more information on the top level and top-level commands.
