Static Variables

[amateurrobotguy]

So, just to recap. I can use extern in the header and declare them at the TOP of userroutines.c. They will be defined once and available to all of userroutines.c as well as anywhere else.
I thought C was run-by-call only. Does C have the exception that it will run everything outside of functions once and then goto rbc only?
My original plan was to delaclare my variables withing userinitialization() to make sure they run get declared once. But if I can just do it outside of all functions and add some stuff to .h and have it work; it is as good as putting it in userinitialization()
