Displays a brief description of each item in the list of objects. If the item is a primitive shape, the type of shape and its vertex are displayed. If the item is a combination, the Boolean formula for that combination - including operands, operators, and parentheses - is displayed. If the combination is flagged as a region, then that fact is also displayed along with the region's ident code, air code, los, and GIFT material code.
The example shows the use of the cat command to display Boolean formulas for two regions.
Example 1. Displaying Boolean formulas for two regions.
cat region_1 region_2
Displays the Boolean formulas for region_1 and region_2.
