Choice Attributes
This section focuses on the attributes available to describe characteristics of choices assigned to gadgets in the choice category. These attributes are maintained as descendants of item and citem and ritem subscripts of the CHOICE attribute. The CHOICE attribute described in the Gadget Attributes section and Table 5.2 list the gadget types that can use these attributes. Example 5.3 shows the syntax for a Choice attribute for nontable gadgets, and Example 5.4 shows the syntax for table gadgets.

The ritem and citem subscripts in Example 5.4 are the row and column subscripts of a choice assigned to the Table gadget. The choice attribute subscript in both examples is a Choice attribute keyword from Table 5.7.

If an application attempts to assign a value for a Choice attribute that is not specified by its domain of values, an error will occur with a code of "M47." [4]
