A table element has a collective
name, but the individual items within it do not have unique
data-names.
To refer to an item, you have a
choice of three techniques:
- Use the data-name of the table element, along with its
occurrence number (called a subscript) in parentheses.
This technique is called subscripting.
- Use the data-name of the table element, along with a value
(called an index) that is added to the address of the table to locate
an item (as a displacement from the beginning of the table).
This
technique is called indexing, or subscripting using index-names.
- Use both subscripts and indexes together.
