The Hobbit (v1.0): Routine at A79F

If Bard has been given an order (8907), it is checked and then written into Bard's own behaviour program: the action ($B5D7), target and instrument ($B5D9, B5DA) are stored at $C8D2-$C8D4, and the first byte at C8D1 is set to $42 (an action instruction that cannot be interrupted by orders). From then on Bard carries out that order every turn. So 'say to bard "shoot the dragon"' keeps him shooting until it works.

SAVE and LOAD (8284, 8209) preserve the three bytes at C8D1-$C8D3, because the behaviour programs are not otherwise saved; the instrument at $C8D4 is not included.
