void loop () decleration problem

@hydrv, the greatest feature of the Arduino system is that it would take only a few minutes to write a sketch to learn what you wanted to know.

This is not meant as a criticism, but rather as advice to use this technique to study things you don't know or new stuff that you want to try with the Arduino.

char testChar = 'S';

void setup() {
  Serial.begin(9600);
  Serial.print("This is in setup() ");
  Serial.println(testChar);
  delay(1000);
}

void loop() {
  testChar = 'L';
  Serial.print("This is in loop() ");
  Serial.println(testChar);
  delay(1000);
}

(I have not tested this).
