CHSETALREADY, CHSETALREADY, Socket device already contains sockets with iCHSET=xxxx, oCHSET=xxxx
Run Time Error: The code tried to create a new socket, specifying a CHSET different than the CHSET previously assigned to the SOCKET device.
Action: If different CHSETs are needed for different sockets, place them in different SOCKET devices. Also, if the CHSET of the SOCKET device needs to be changed, it can be done with OPEN/USE command which doesn't create a new socket.
