Yes, I agree with the approach to using __RCX for conditional compile -
that's really why its there.
I had thought about adding some of the functions (SetSensor() etc.) as
no-ops in the Scout API, but this really didn't feel right to me. I
figured someone could build their own API which no-oped things
accordingly, but I didn't want to take the official API in this
direction. Really more of a philisophical thing.
Incidentally, the __RCX symbol is currently either defined or undefined.
Soon it will be defined to a certain value indicating the firmware level
of the RCX - for example...
#if __RCX == 1
// RCX 1.0 firmware (actually 3.09)
#elif __RCX == 2
// RCX 2.0 firmware (3.21 or better)
#endif
Again, in cases where the functionality present in 1.0 and 2.0, the API
will exist in both. However, new features for 2.0 will have no
corresponding API in 1.0 builds, so using them (without the appropriate
conditional compile) will cause an error.

| Have you considered adding the firmware build version to that symbol or to a new one? __RCX = 2 __FIRMWARE=3.21 This would facilitate creation of portable, work-around code that would accomodate an end-user who hasn't updated their firmware (or has (...)
