    "The startup file normally calls the initialization function of the C library.
    The initialization function of the C library normally calls main()."

    Somewhere in that chain is also the thing that initialises the user's 'C' variables...

    So, back to Erik's point, you really should make sure that you have a main() function in 'C' as your programs "entry point" - which was effectively also my point in saying, "you would generally just be calling from 'C' to assembler; not vice-versa"
