Steve:

I’m tinkering with your program and there is line that I don’t fully understand:

cOutput='c'+chr(val('0x'+cHC)+0x40)+chr(val('0x'+cUC)+0x40)+chr(val('0x'+cFC)+0x40)+chr(val(num_hexa(1))+0x40)

the “num_hexa(1)”, I have not found where is it coming from

Could you shed some light on it form me?

Thanks

BDH
