The FrameLabel tag gives a textual name to a frame. This name can also be used as an anchor in V6.x+ and whenever specified in this way.
At this time, the optional field f_flags must be set to 1 if present. This means it has to be used as an anchor when the URL to the SWF movie includes a
#<frame label> at the end.
The f_label is a null terminated string.
