Changing frames in one SWF from a second SWF?

programming flash

Suppose I’ve got 2 SWF files, SWF 1 and 2. SWF 1 has several frames in it. Is it possible to use buttons in SWF 2 to change frames in SWF 1, and if so, what code would I use? Looking for solutions in AS2 + thanks for reading :smiley:
