914A: Are attacker and target on the same side?
Used by the routines at DO_SHOOT and DO_ATTACK.
Bits 4 to 6 of byte 4 of each record are the sides; sharing one ends the handler that called this with SUCCEEDED clear -- it would not work. The player alone can turn on a friend: attacked by the player, a character on the player's side (bit 4) is taken off it first, so the attack goes ahead and it is an enemy from then on.
SAME_SIDE 914A LD IX,(TARGET_RECORD) The player attacking a friend: no longer a friend
