F9BB: Check whether ERIC has 10000 lines
Used by the routine at 76F9. The number of lines has just been printed. Has ERIC gone over the limit?
Input
Output
F9BB LD A,($7FC7) Collect the MSB of the lines total
F9BE CP $03 Is the lines total < 7680 (30*256)?
F9C0 RET C Return if so
F9C1 JR NZ,$F9C9 Jump if the MSB > 3 (lines total > 10240)
F9C3 LD A,($7FC6) So the MSB is 3; collect the LSB from 7FC6
F9C6 CP $E8 Is the lines total < 10000 (=232+256*30)?
F9C8 RET C Return if so
ERIC has 10000 lines or more. The end (of the game) is nigh.
F9C9 PUSH HL
F9CA LD HL,$FAE2 Point HL at the first of the last two commands in command list 0xDE ('Find ERIC', and 'Send ERIC home')
F9CD LD ($A377),HL Place this address into bytes 0x77 and 0x78 of MR WACKER's buffer, so that these commands become his command list
F9D0 LD HL,$A37A Set bit 0 of byte 0x7A of MR WACKER's buffer, triggering a command list restart
F9D3 SET 0,(HL)
F9D5 LD HL,$7FF8 Set the MSB of the lesson clock to 0xFF (so that the lesson cannot end before MR WACKER has begun looking for ERIC)
F9D8 LD (HL),$FF
F9DA POP HL
F9DB RET
