A | Character number of lines recipient |
B | Lines message identifier (0-15) |
DE | Coordinates of teacher dishing out lines |
30464 | PUSH BC | |
30465 | PUSH AF | |
30466 | CALL 29871 | Is the lines-giving teacher fully on-screen? |
30469 | JR NC,30474 | Jump if so |

30472 | POP BC | |
30473 | RET | Otherwise return without having given lines |
The teacher is on-screen, so it's time to prepare the lines bubble for display. First, write the lines recipient's name into the lines bubble graphic buffer.

30474 | POP AF | |
30475 | PUSH DE | Save the attribute file address of the lines bubble |
30476 | PUSH AF | Save the character number of the lines recipient |
30477 | CALL 30208 | Write the recipient's name into the lines bubble graphic buffer |
Next, determine how many lines should be given.
