Use volatile to force the compiler to avoid optimising the memory lookup away

I think the above suggestion is made in relation to the use of a separate function - which is not the method I've adopted. (I've made use of a temp variable, but it's in the body of the function itself, rather than in a separate function.)

I find that declaring my temp variable as "volatile" doesn't help me. If I get rid of the #pragma optimize() calls, and declare the temp variable as volatile float temp, the problem remains. Obviously, "volatile" doesn't turn off every kind of optimization, and certainly doesn't turn off the kind of optimization that it needs to (in my case).

Cheers,
Rob
