Hi Erik,

in answering exact to your question:

Real C programmers have no morbid fear of global variables.

If global variables are advantageous, they use it.
But often the other way give more advantages, e.g. faster and smaller code (variables in registers) or less RAM usage (overlaying variables).

Also, if a value was returned over 7 functions, nothing happen with it, since already in a register. So only seven returns executed, nothing more.
