> ## Accessing user-defined function return values

> You can access the return value after running any user-defined function using the `ReturnValue` property on the `Progress.Open4GL.Proxy.ParamArray` object. For example:

> Syntax
>     public System.Object ReturnValue

> You need to cast the return `Object` to the correct return type for the function. For example:

>     string retVal = (string) parms.ReturnValue;
