http://wiki.srb2.org/wiki/THZ2_Slime_Raise[/url]]Sector Type 986, THZ2 Slime Raise, is an obsolete sector type used for the red button in Techno Hill Zone Act 2. B = Button, W = Water (slime in this case), P = Platform, D = Door, S = Sign. Works kind of like doors (sector types 690-709). Any sector with tag 712 is assumed to be the button, B, and is lowered. Any sector with tag 713 is assumed to be the water/slime, W, and is lowered. And so on. Since Linedef Executors can mimic this effect, and give the editor more overall control, this sector type is obsolete, and the use of Linedef Executors is recommended over it.
