32<H2>Description</H2>
33<P>This function allows you to declare a callback that is invoked when a graphics display list overflows. Overflow is detected only when you attempt to write to a <a href="GDLObj.html"><CODE>GDLObj</CODE></a> structure and the upper limit for the memory buffer associated with the current location pointer is exceeded (or when the limit may be exceeded as a result of writing).</P>
34<P>If an overflow callback is not declared, the default overflow process will force an assertion failure. (Debug build only.)</P>
