Bulk reset vriables to default

[J-M-L]

something like this:

int x, y , z; // zero initialized by the compiler

void reset2Defaults() {
  x = 3;
  y = 6;
  z = 9;
}

void setup() {
  reset2Defaults();
  ...
}

void loop() {
  ...
}

and in the loop, when you want to revert to the defaults, you call reset2Defaults()
