Plenty of program memory...but after spending 3 days fixing bugs and
starting to get somewhere with the Reconfiguration the thought of having to
add more code wasnt very appealing......Has anyone done any config stuff
using PBP or Proton+ ??? ......also writing to the program memory i find a
little scary.... wouldnt want a power failure when this is happening.......

Dont worry will leave provision for 16 bytes in my tables for the
instance.........
Thanks
