That's what I was looking for. Everything compiled just fine. Thanks a bunch!

Alternatively, you could use pointers. Declare variables in main.c, declare pointers to them, and pass said pointers to the ProcessDatefrommasterUP and processdatafrommasterIO functions. Then pass them from there to whatever other functions you want to have access to those vars.
