/*
**	Purpose:
**		Radio Button Group Dialog procedure for templates with one group
**		of one to ten radio button controls.
**	Control IDs:
**		The Radio button controls must have sequential ids starting with IDC_B1
**		and working up to a maximum of IDC_B10.
**		Pushbuttons recognized are IDC_O, IDC_C, IDC_M, IDC_H, IDC_X, and IDC_B.
**	Initialization:
**		The symbol $(RadioDefault) is evaluated as an index (one-based) of
**			the radio button to be set on.  Default is 1.
**		The symbol $(OptionsGreyed) is evaluated as a list of indexes
**			(one-based) of radio buttons to be disabled (greyed).  Default is
**			none.
**	Termination:
**		The index of the currently selected radio button is stored in the
**		symbol $(ButtonChecked).  The id of the Pushbutton (eg IDC_C) which
**		caused termination is converted to a string and stored in the
**		symbol $(ButtonPressed).
