Pop two strings, compare them, push the Boolean result back on the stack.

This operation was available since version 4 of SWF. Since Macromedia introduced String Greater Than (typed) in version 6, it is likely that this operator is expected to legally be used, although it seems to me that the Less Than (typed) action should be used instead.
