### 17.2.1. Power Syntax Subroutine Descriptions

In the next section, each subroutine will appear in the following format:

Each of the subroutines contains an argument list (in brackets, separated by commas). If any argument contains more than one word (for example, `Plane 1`), it must be within quotes. You should enclose all arguments within quotes to avoid making possible syntax errors.

Each subroutine is preceded by its return value(s). For example:

    real, string evaluate("Expression", "Locator")

will return two values, a real number and a string.

The return values will always be in the solution units of the CFX-Solver results file, even if you have changed the display units in the Edit menu. This means that if you have a plot of temperature in degrees C on `Plane 1`, the area averaged value of temperature on `Plane 1` returned by the `areaAve` command will still be in degrees K.
