<DT><B> Synopsis </B><DD><P>Reset the interpreter after an error
<DT><B> Usage </B><DD><P><CODE>void SLang_restart (int full)</CODE>
<DT><B> Description </B><DD><P>The <CODE>SLang_restart</CODE> function should be called by the
application at top level if an error occurs.  If the parameter
<CODE>full</CODE> is non-zero, any objects on the <B>S-lang</B> run time stack
will be removed from the stack; otherwise, the stack will be left
intact.  Any time the stack is believed to be trashed, this routine
should be called with a non-zero argument (e.g., if
<CODE>setjmp</CODE>/<CODE>longjmp</CODE> is called).
<P>Calling <CODE>SLang_restart</CODE> does not reset the global variable
<CODE>SLang_Error</CODE> to zero.  It is up to the application to reset
that variable to zero after calling <CODE>SLang_restart</CODE>.
