How do I preserve the data in the internal EEPROM when reprogramming? I'm using an 18F452.

What programmer are you using ?
If you are using ICD2, then pick the Settings menu
under either Debugger or Programmer menus.
(You have to select ICD2 as the Debugger or Programmer
to get the Settings menu to be enabled.)
Then within the Settings window, click on the Program tab.
It contains an option to protect the EEPROM from being
programmed by the ICD2. |

For ICDU40, open up ICD.EXE, click on the 'Advanced...' button, in the 'Erase Modes' section choose 'Erase When Needed'. |
