Hi All! Hi Sir Richard !
I'm wondering about something : What is happening when Decrementing 0h ? I saw it from a book, but there is no explaination of the process. it is just said the results,when decrementing 0h the result, would be 256 ! I found it when reading about some loops. Cyrille, What you have will decrement memory location 0H and the result is undefined, unless you say that 0H contains 0 to begin with. After the DEC, 0H will contain 255 (0FFH), not 256, which would need 9 bits. Steve |

| Good! Erick | 01/01/70 00:00 | |
| why work from print | 01/01/70 00:00 | |
| I do ! | 01/01/70 00:00 | |
| Surely that's justification enough. | 01/01/70 00:00 | |
