XI (doc): ServerController short hand
I will let the comment speak for itself.
gServerController: TIWServerControllerBase = nil;
// gServerController was too much to type all the time, but we keep the old one
// so we don’t break code. But now you can access it as gSC as well.
// gSC = gServerController
gSC: TIWServerControllerBase = nil;
