+      linkend="enable-sql-reader-syntax">
+      <function>enable-sql-reader-syntax</function></link> and <link
+      linkend="disable-sql-reader-syntax">
+      <function>disable-sql-reader-syntax</function></link> which try to keep track of whether
+       the syntax has been enabled or disabled and keep track of the old read-table for restoration this function just enables it unconditionally.
+      </para>
+      <para>Once enabled this way there is no corresponding disable function but instead relies on being used in a file context. The spec for <ulink url="http://www.lispworks.com/documentation/lw51/CLHS/Body/f_load.htm">load</ulink> and <ulink url="http://www.lispworks.com/documentation/lw51/CLHS/Body/f_cmp_fi.htm">compile-file</ulink> states that the *readtable* will be restored after processing the file.
