#150910 - once DPTR points to that value... Responding to: ???'s previous message |
... it's simply: movx a,@dptr inc a movx @dptr,a If it would be a two-byte variable, it would be: movx a,@dptr add a,#1 movx @dptr,a inc dptr movx a,@dptr addc a,#0 movx @dptr,a etc. Have fun! JW |

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 | |
