Michael,

I agree with you.

However, as you mentioned, I have to take care of the SP initialization as of the nesting level of subroutines and interrupts witch is a little unusual in a C environment ( of course not impossible but need a deep understanding of C’s libraries).
To take full advantages of the VRS700’s facilities and still easily working in C, I thing a modification to the compiler ( or linker) must to be made .
The user would have to use a switch or a pragma directive.

Regards,
Cristian
