LotusScript Classes
LotusScript can be divided into two classesfront-end and back-end. The front-end class enables you to access an object via the Lotus Notes client interface. The back-end class, on the other hand, enables you to manipulate an object independently of the user interface. Using this class, you can manipulate objects stored in the database. For example, a Notes document that LotusScript accesses from the front-end is often called uidoc (or user interface doc), whereas the same document accessed from the back-end is often called simply doc.
With this important distinction in place, next I'll discuss the primary terminology, constructs, and general syntax that comprise the LotusScript language. As with all programming languages, LotusScript includes keywords, variables, constants, operators, comments, subroutines, and functions.
