mem - how did you get your example to be in colour?
to get the syntax coloring, from the ide edit menu, select 'copy for forum'
Serial.print("x ");
Serial.print(x);
Serial.print(" y ");
Serial.print(y);
Serial.print(" z ");
Serial.println(z);
I think beginners find that ungainly.
There has got to be a better way that does not look scary.
