Yes, you have to return the value from your function. But then, if you
don't store this value somewhere, it's lost. What you have to understand
is that you actually have *2* variables named 'firstMsg' : one in the
'main loop', and one in PID_MinMax(). Rebinding the second name has no
impact on the first. So you have to explicitely assign the return value
of PID_MinMax() to the main loop's firstMsg variable. Else, this value
is simply discarded.
