Using @functions

Notes® @functions are built-in formulas that perform specialized calculations and return a value. The following sections describe:

For individual @functions, see the topic @Functions. For individual @commands see the topic @Commands.

Syntax
The general format of an @function is:
Return values and @functions
An @function calculates a return value and replaces itself with the value. The use of the @function must be appropriate for its data type. For example, @Power can compute the value of a numeric field:
Side-effects
A side-effect is an action that occurs outside the immediate scope of the formula. For example, @Prompt displays a dialog box in addition to returning a value. Make sure that a side-effect occurs at the correct point of a formula's execution.
@Commands
The @Command and @PostedCommand functions execute a Notes command. The first argument to @Command or @PostedCommand is a keyword argument that specifies the Notes command. Depending on the Notes command, other arguments may be required.
Order of evaluation for formula statements
Domino evaluates formulas from beginning to end and left to right, completing each statement before proceeding to the next, except that @PostedCommand and a few @Command functions are executed in order after all other @functions complete execution. Formula language contains several @functions for control logic.
