to move a player to another room, insert it after the room's firstplayer and increase the room's players amount
room(1,1)-> player player room(2,1)-> player room(3,1)-> player player player player so room(1,1) would have 2 players so room(2,1) would have 1 player so room(3,1) would have 4 players
to go though all players in the room: p=curroom\firstplayer for a=1 to curroom\players writeline p\stream, message$ p=after p next
to move a player to another room, insert it after the room's firstplayer and increase the room's players amount
