I believe this is for simulation and debugging, > and does not actually set the bits. The dialog that pops up when you try to program with a Picstart+ does effect the config word. That's its job. It allows you to specify the production settings in the code, but override them for individualy programming sessions for the purpose of debugging. The settings in the code then become the default for the dialog. I find that a handy way of verifying that the config word is specified properly in the code. However, I'm not sure what happens if the config word is not specified at all (no __CONFIG directive). Perhaps then it's left alone, which would leave it all 1s after the erase. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com#nomail Going offline?
