Jumper,

A few basic questions about your file:

1) "DEFINE LOADER_USED 1 'Sets loader at address defined in Library file"
Does this refer to a modified library file as explained earlier in this thread?

2) "RB6 var PORTB.6; RB7 var PORTB.7"
I assume these are just 'flag' bits to tell you which mode the chip is in?

3)"IF temp=$FFFF then STOP"
What happens after the 'STOP'?

4) "@GOTO 0x0040"
Why 0x0040?'

5) "'Erase before writing and write full blocks 64 bytes"
Do you suggest writing the erase and program code in assembly, or can it be done in PBP?
