Mining Turtle Persistence

My server crashes now and again stopping all of my computer programs. Every time my turtle moves it records its x,y,z and direction in a file, so that it can call on this info if the server resets.

My question is, is it possible to run the 'return' code when the server boots back up? From what I can see you need to click a computer to turn it on, to even run the "startup" code. Which means I still have to go and find my turtle each time. Pastebin links to my mining code and the startup code below.

Have a file which the program reads to check if it was interrupted?

Yep I do have that file, if the turtle was interrupted then the "GPS" file will exist (if it finished it's job that file wont exist). I actually think this is solved, as last time the server restarted the turtles automatically ran their startup code when I went to the chunk the turtle was in (even though it is chunk loaded). So I guess that is good enough, if they resume when I got to the chunk
