Given two sets A and B, the
UNION function returns a new set "A-plus-B", that is all the domains that are only in A plus all the domains that are only in B plus the domains that A and B have in common.
For example, given these two sets:
setOne: 1 1.01 1.15 1.17 setTwo: 1.01 1.15 1.18
var union = UNION(setOne, setTwo);
defines and populates the
union set this way:
1 1.01 1.15 1.17 1.18
The syntax is:
set2 are set variables.
