Referencing Table Elements
Whenever the user refers to a table element, or to any item associated with a table element, the reference must indicate which occurrence is intended.
For a one-dimensional table, the occurrence number of the desired element gives the complete information. For tables of more than one dimension, an occurrence number for each dimension must be supplied. In the three-dimensional table defined in the previous discussion, for example, a reference to ELEMENT-THREE must supply the occurrence number for ELEMENT-ONE, ELEMENT-TWO, and ELEMENT-THREE.
