Thanks guys - you have answered almost all the questions Ray had :-) .

When doing a verify, you will definitely get an error when the chip was code-protected before, as the data read back are scrambled. On the other hand, you may also get verify errors with unprotected chips. In this case, it is most likely that the chip was programmed with a different program before, or with different DEVICE settings. Before running a verify, you need to load the SRC file into the IDE, and have it assembled in order to fill the IDE's internal program buffer with the matching data. During verify, the contents of this buffer is compared against the data read from the chip's program memory.

As mentioned in some other threads, it is recommended _not_ to use the Device dialog for programming chips. Always use the IDE's "Program" option. This makes sure that the device settings are programmed according to the DEVICE directives in the program code, and not to the settings in the Device dialog.
