None. <P>
<P><B>Description:</B><P>
<P>
The intent of the <A REL=DEFINITION HREF="a_abort.htm#abort"><B>abort</B></A> restart is to allow return to the innermost ``command level.'' Implementors are encouraged to make sure that there is always a restart named <A REL=DEFINITION HREF="f_abortc.htm#abort"><B>abort</B></A> around any user code so that user code can call <A REL=DEFINITION HREF="f_abortc.htm#abort"><B>abort</B></A> at any time and expect something reasonable to happen; exactly what the reasonable thing is may vary somewhat. Typically, in an interactive listener, the invocation of <A REL=DEFINITION HREF="f_abortc.htm#abort"><B>abort</B></A> returns to the <A REL=DEFINITION HREF="26_glo_l.htm#lisp_reader"><I>Lisp reader</I></A> phase of the <A REL=DEFINITION HREF="26_glo_l.htm#lisp_read-eval-print_loop"><I>Lisp read-eval-print loop</I></A>, though in some batch or multi-processing situations there may be situations in which having it kill the running process is more appropriate. <P>
