| no need to put constant into dptr | 01/01/70 00:00 | |
| How can I get the low and high parts? | 01/01/70 00:00 | |

| push/pop A | 01/01/70 00:00 | |

| options: | 01/01/70 00:00 | |
| By inc I mean increase the value in RAM by 1 | 01/01/70 00:00 | |
once DPTR points to that value... | 01/01/70 00:00 | |
| this is why it's dangerous... | 01/01/70 00:00 | |
| You can push/pop [direct] though. | 01/01/70 00:00 | |
| this is certainly correct... | 01/01/70 00:00 |
