Return

Use the Function part to start a function and the Return part to finish it.

By default, the Return part does not return any value, but you can configure the function you have constructed to return some value when it is called. This can be:

• a value
• a variable
• an expression.

When the Return part is reached, the value (or worked out variable or expression) is returned to be used in the calling expression.

Tips for use:

• Most of the built-in functions return values. For instance, sqrt(x) returns the square root of x.
• If a function is called from within an expression, the function must return a value. If a function is called from a Call function part, then any return value will be ignored.
