I'm not totally sure about this, but try playing around with #define
In one language I use, the compiler will totally take out the variable, and put in
the defined value, before compiling the program. I assume that's how it should work
in C and NQC.
So, you can do this:
---
#define UseColor >
// '>' is black line
// '<' is white line
...
if (s1 UseColor threshold1)
{
// s1 is on line
}
else
{
// s1 is off line
}

For Chibots advanced line, they usually have a hump that's about 2 inches high, in
the middle, and 6 to 8 inches long.
