I just had a look and I have these in my program : - looks like I was wrong about the DEFINE command - it should be DEFINE RESET_ORG

DEFINE OSC 48
DEFINE LOADER_USED 1
DEFINE RESET_ORG 1000h ' For Microchip USB Bootloader


bill.
Yesssss

Of course DEFINE RESET_ORG 1000h
That was missing... my mistake

I'm glad, so glad that this was the only fault. Not a big struggle or .....

Thank you so much Bill, thank you indeed!
