141<H2>Description</H2>
142<P>This function selects the constant alpha input to be used on the given TEV stage. The constant alpha input is only used when <CODE>GX_CA_KONST</CODE> is selected as that TEV stage input. It can be used for one or more inputs, but only one constant alpha input can be used for one TEV stage.</P>
