What Are Functions and Commands?

Formula Language can be divided into two groupings@Functions and @Commands.These groupings comprise Formula Language and are used to create formulas.

Functions are used to return a value and can be placed anywhere within a formula. Although most functions simply return a value, some functions interact with users or trigger other actions to occur. For example, the @Prompt and @PickList functions can be used to request input from the user.

As you gain experience with Formula Language, you'll find that most formulas are built using functions. However, some functions can only be used in specific design objects. The following table lists some of the restricted functions and describes where they can be used.

Note

A select number of functions can be called from LotusScript or have equivalents in LotusScript. Functions are sometimes called from LotusScript to simplify the code instructions. In other words, a single @Function can often replace multiple LotusScript code. In other cases, there are equivalent functions already included in the LotusScript language.
