/*
**  Purpose:
**      CheckBox Dialog procedure for templates with one to ten checkbox
**      controls.
**  Control IDs:
**      The Checkbox 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 $(CheckItemsIn) is evaluated as a list of elements of
**          either 'ON' or 'OFF'.  So examples for a template with four
**          checkbox controls would include {ON, ON, ON, ON},
**          {ON, OFF, ON, OFF} and {OFF, OFF, OFF, OFF}.  These elements
**          determine if the initial state of the corresponding checkbox
**          control is checked (ON) or unchecked (OFF).  If there are more
**          controls than elements, the extra controls will be initialized
**          as unchecked.  If there are more elements than controls, the
**          extra elements are ignored.
**      The symbol $(OptionsGreyed) is evaluated as a list of indexes
**          (one-based) of check boxes to be disabled (greyed).  Default is
**          none.
**  Termination:
**      The state of each checkbox is queried and a list with the same format
**          as the initialization list is created and stored in the symbol
**          $(CheckItemsOut).
**      The id of the Pushbutton (eg IDC_C) which caused termination is
**          converted to a string and stored in the symbol $(ButtonPressed).
