Message code 02. Steps the message pointer by a signed byte. Reached through the control-code table at PrintTable, dispatched by PrintMessage.
|
||||
| Message_StepByASignedByte | 737E | LD E,(IX+$01) | Jump to Message_StepByASignedByte_ApplyTheOffset if bit 7 of the message byte at offset 1 is clear. | |
| 7381 | LD D,$00 | |||
| 7383 | BIT 7,E | |||
| 7385 | JR Z,Message_StepByASignedByte_ApplyTheOffset | |||
| 7387 | LD D,$FF | The offset is negative, so the high byte is FF. | ||
| Message_StepByASignedByte_ApplyTheOffset | 7389 | ADD IX,DE | Step the message pointer by the signed byte. | |
|
Codes 05, 0A, 0F and 12 come straight here through the control-code table at PrintTable and do nothing.

| Message_StepByASignedByte_FinishOrIgnoreTheCode | 738B | XOR A | Finish this control code with zero. | |
| 738C | RET | Return. | ||
