Use the ORDINAL attribute to declare a variable with an ordinal type. The format is:
{ORDINAL|TYPE} ordinal-type-name
Where ordinal-type-name is the name of a defined set of ordinal values.
Some other data attributes, such as FIXED or SIGNED, conflict with ORDINAL; however, no conflict exists with others such as BASED or DIMENSION.
See Example 3 in the DEFINE ORDINAL topic.
