Do you know what specific source code it being compiled to live within the bootloader area? Or is the problem just that the IVT code is not being placed into the relocated area? Or is it something else? It might help to create a *very* simple example of the issue in MPLAB and replicate it in Flowcod...

If you have a trailing comma and then a newline, Flowcode sees this as having nothing between those 2 delimiters and inserts a zero. (I might change Flowcode so a future release will treat a comma followed by a newline a...
