Formula syntax rules

The UCE formulas conform to the following syntax rules:

• A UCE formula can reference almost any service point channel at any service point in the system, including other formula channels.

• UCE formulas support multiple levels of nesting, including the @if functions.

• Wherever a channel argument is required for a UCE function, the argument can be a service point channel, a formula that evaluates to a channel of values, or a constant that is applied to each interval.

• Constants used in formulas can be values, or they can be references to named constants.
