Fnd_Gen_ComponentAvailable

            Fnd_Gen_ComponentAvailable (component name) ➔ Boolean

              Parameter               Type              Description
              component name          Text              Name of the component
              Function result         Boolean           True if the component is available

            Use the Fnd_Gen_ComponentAvailable routine to determine if a specific Foundation component
            is available. If it is, you can then call the component using 4D’s EXECUTE command. This allows
            your method to behave differently if a component is available, yet still compile without the component
            installed.
            You can also make your own routines compatible with this routine by creating an initialization routine
            that ends with “_Init.” For example, if you create a component named “MyComponent,” just create a
            routine named “MyComponent_Info.” It does not matter what it does — it is only important that it does
            not cause an error, or at least resets 4D’s Error variable to 0. You can then test for the component this
            way:
              If(Fnd_Gen_ComponentAvailable ("MyComponent"))
                EXECUTE("MyComponentMethod")
              End if

            See the source code to Foundation’s Fnd_Gen_MenuBar method to see how this function can be used.
