FORMULA LANGUAGE


Working with @functions
All @functions evaluate to a value and can be placed in a formula anywhere a value of that type can be placed. When the formula executes, the value of the formula takes the place of the formula. Some formulas also have side-effects, that is, they cause actions to occur. For example, @Prompt causes a message box to appear.

Most @functions can be used in formulas for any Notes object, but some @functions are restricted in their applicability. The following table lists the @functions that are restricted and lists the Notes objects in which they can be used effectively. In addition, for an @function to return information on the current database, view, document, or field, these objects must be current.
