Result Type: Selection
Definition: Creates a union of the two selections (which must be from the same internal file). The second parameter can be specified as an existing selection, or as a search that results in a selection. The resultant selection can be optionally sorted in the same way as createSelection().
Example: If sel1 is a selection created by
i.e. of cash payments
returns a selection containing both cash payments and receipts, and is equivalent to
createSelection("transaction", "type=`CP` or type = `CR`)
unionSelection(sel1, "type=`CR`", "transdate")
Same as previously, except the selection is sorted into ascending order of transaction date (for descending order, pass a fourth parameter with a value of 1).

DisplaySelection: Display standard list window for a given selection of records
IntersectSelection: Intersect a selection with the result of another search
RecordsSelected: Count records in a selection or resulting from a (meta) search
