Used by the routine at 30457. The number of lines has just been printed. Has ERIC gone over the limit?
Input
Output
63931 LD A,(32711) Collect the MSB of the lines total
63934 CP 3 Is the lines total < 7680 (30*256)?
63936 RET C Return if so
63937 JR NZ,63945 Jump if the MSB > 3 (lines total > 10240)
63939 LD A,(32710) So the MSB is 3; collect the LSB from 32710
63942 CP 232 Is the lines total < 10000 (=232+256*30)?
63944 RET C Return if so
ERIC has 10000 lines or more. The end (of the game) is nigh.
63945 PUSH HL
63946 LD HL,64226 Point HL at the first of the last two commands in command list 222 ('Find ERIC', and 'Send ERIC home')
63949 LD (41847),HL Place this address into bytes 119 and 120 of MR WACKER's buffer, so that these commands become his command list
63952 LD HL,41850 Set bit 0 of byte 122 of MR WACKER's buffer, triggering a command list restart
63955 SET 0,(HL)
63957 LD HL,32760 Set the MSB of the lesson clock to 255 (so that the lesson cannot end before MR WACKER has begun looking for ERIC)
63960 LD (HL),255
63962 POP HL
63963 RET
