| 62517 | 3D | DEC A | 0≤A≤3 |
| 62518 | 21785C | LD HL,23672 | Point HL at the LSB of the system variable FRAMES |
| 62521 | EE02 | XOR 2 | Flip bit 1 of A |
| 62523 | CB7E | BIT 7,(HL) | |
| 62525 | 2802 | JR Z,62529 | Jump if the LSB of FRAMES is < 128 |
| 62527 | C604 | ADD A,4 | 4≤A≤7: force lowercase (slow) keypress |
| 62529 | 87 | ADD A,A | A=80+2n where 0≤n≤7 ("simulated" keypress for LEFT, RIGHT, UP, DOWN or left, right, up, down) |

| 62538 | 2100D2 | LD HL,53760 | |
| 62541 | 2806 | JR Z,62549 | Jump if little boy no. 10 is sitting in a chair |
| 62543 | FEC5 | CP 197 | 197: Is little boy no. 10 sitting on the floor facing right (as in assembly)? |
| 62545 | 2802 | JR Z,62549 | Jump if so |
| 62547 | AF | XOR A | No simulated keypress (ERIC stays still) |
| 62548 | C9 | RET | |
| 62549 | AE | XOR (HL) | Set carry if ERIC and little boy no. 10 are facing in opposite directions |
| 62550 | 07 | RLCA | |
| 62551 | 3E62 | LD A,98 | 98=keypress code for 'S' (sit/stand) |
| 62553 | D0 | RET NC | Return if ERIC and little boy no. 10 are facing the same way |
| 62554 | 7E | LD A,(HL) | A=ERIC's animatory state |
| 62555 | 07 | RLCA | Set A to 1 if ERIC is facing left (leading to a simulated keypress code of 82, or RIGHT), 0 if he's facing right (leading to a simulated keypress code of 80, or LEFT); that is, make ERIC turn round |
