Several <A REL=DEFINITION HREF="26_glo_r.htm#readtable"><I>readtables</I></A> describing different syntaxes can exist, but at any given time only one, called the <A REL=DEFINITION HREF="26_glo_c.htm#current_readtable"><I>current readtable</I></A>, affects the way in which <A REL=DEFINITION HREF="26_glo_e.htm#expression"><I>expressions</I></A>[2] are parsed into <A REL=DEFINITION HREF="26_glo_o.htm#object"><I>objects</I></A> by the <A REL=DEFINITION HREF="26_glo_l.htm#lisp_reader"><I>Lisp reader</I></A>. The <A REL=DEFINITION HREF="26_glo_c.htm#current_readtable"><I>current readtable</I></A> in a given <A REL=DEFINITION HREF="26_glo_d.htm#dynamic_environment"><I>dynamic environment</I></A> is the <A REL=DEFINITION HREF="26_glo_v.htm#value"><I>value</I></A> of <A REL=DEFINITION HREF="v_rdtabl.htm#STreadtableST"><B>*readtable*</B></A> in that <A REL=DEFINITION HREF="26_glo_e.htm#environment"><I>environment</I></A>.
