For backward compatibility the <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> provided by the current Tk version still tries to call <B>tkerror</B> if there is one (or an auto loadable one), so old script defining that error handler should still work, but you should anyhow modify your scripts to use <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> instead of <B>tkerror</B> because that support for the old name might vanish in the near future. If that call fails, <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> posts a dialog showing the error and offering to see the stack trace to the user. If you want your own error management you should directly override <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> instead of <B>tkerror</B>. Documentation for <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> is available as part of Tcl's documentation. <H3><A NAME="M5">KEYWORDS</A></H3> <A href="../Keywords/B.htm#background error">background error</A>, <A href="../Keywords/R.htm#reporting">reporting</A> <HR><PRE> <A HREF="../copyright.htm">Copyright</A> © 1990-1994 The Regents of the University of California. <A HREF="../copyright.htm">Copyright</A> © 1994-1996 Sun Microsystems, Inc. <A HREF="../copyright.htm">Copyright</A> © 1995-1997 Roger E.
