Used by the routine at 38009.
38480 LD IX,44162 Load IX with address of complex state data for ape-beast 1 (level 2)
38484 LD IY,38424 Point IY at table of current positions in ape-beasts' script data
38488 LD A,(IX+1) If depth of ape-beast is zero (i.e. ape-beast killed by Bubo)...
38491 OR A ...
38492 JR Z,38523 ...then skip ahead to 38523 (i.e. move onto next ape-beast)
38494 LD L,(IY+0) Load HL with current position in script data for current ape-beast...
38497 LD H,(IY+1) ...
38500 LD (34277),HL ...and store at 34277 as position in script currently running

38514 LD HL,(34277) Store address (current position in script data for current ape-beast) stored at 34277...
38517 LD (IY+0),L ...in table at 38424 as current position in this ape-beast's script data...
38520 LD (IY+1),H ...
38523 INC IY Advance IY to next entry in table (i.e. position in next ape-beast's script data)...
38525 INC IY ...
38527 LD DE,13 Advance IX by 13 bytes (i.e. to entry for next ape-beast)...
38530 ADD IX,DE ...
38532 LD A,(IX+8) If class of this next entry is 25 (i.e. ape-beast)...
