Many thanks - I think solution #1 is the way to work, as any future project will pick up the copy - assuming that freezing generated code will only work for current project.
I know that I can't go to 10.3 in Linux - sad though it is for me. When working on my desktop machine, I run 10.3 in a Windows virtual machine. My laptop, however, isn't powerful enough for this, so for the HCS08 projects that I need to run between the two machines, I'm stuck with 10.2
Thanks again for this solution!
