A common operator used in programming, it is used in conjunction with an "IF" statement. When read in "english", it is something like "IF this happens, do something, ELSE, do something different". HotDocs supports ELSE and ELSE IF expressions. DealBuilder supports use of ELSE in calculation, but relies on NOT for conditional expressions. GhostFill has no ELSE construct, but uses a DeleteBlockIf function or an IfTrue(condition,true result,false result).
