The CLONE function returns a new set that is an exact copy of an existing set.

For example, this statement:

workingSet = CLONE(ALL);

defines and populates workingSet with a copy of the contents of the predefined set ALL.

The syntax is:


where set is a set variable.


In the manipulation flow, CLONE is used both in the first instruction—to create a working copy of the ALL set—and in the last—to copy the contents of a working set in the WINNERS set.
