Wouter,
Thanks for the tip. I checked a bit deeper into a few things..
Found some interesting omissions in the Microchip include
file for P18f248, as follows

_CONFIG4L did not have config options for the following
_LVP_ON_4L        EQU    H'FF'
_LVP_OFF_4L        EQU    H'FB'
_BKBUG_ON_4L    EQU    H'7F'
_BKBUG_OFF_4L    EQU    H'FF'

After adding these to the .inc file, I tried the following hack to
mask the unused bits to zero. (I'm open for critiques here)
#define _fix1l    0x00
#define _fix1h    0x27
#define _fix2l    0x0f
#define _fix2h    0x0f
#define _fix3l    0x00
#define _fix3h    0x00
#define _fix4l    0x85
#define _fix4h    0x00
#define _fix5l    0x0f
#define _fix5h    0xc0
#define _fix6l    0x0f
#define _fix6h    0xe0
#define _fix7l    0x0f
#define _fix7h    0x40

Then I &'ed each to it's respective config byte.
The "new" config words compiled fine, and
checked OK with the MPLAB config window.

I reloaded the new hex file into PicallW, and still
got the same errors. Enter troubleshooting mode:

Load a known good hex file for PIC16F877, try
to dump it to a chip, same errors.
Revert to previous version of PicallW, same hex file
same chip, same P16PRO, works fine.

The trouble must be the new version of PicallW (0.13d)

I've reported the trouble to the author of picall. I hope to
get it resolved soon, I hate being stalled.

Thanks again for the help, and I hope others can benefit from
the missing Config options that I mentioned above

Lyle
