An algorithm designed for an automated weather station uses a RECORD structure to store information about weather sensors.

RECORD SensorNode
    nodeName : String
    elevation : Integer
    statusCode : Character
    batteryLow : Boolean
ENDRECORD

node1 ← SensorNode('North_Ridge', 1420, 'A', False)
node2 ← SensorNode('Valley_Flow', 450, 'F', True)
node3 ← SensorNode('East_Slope', 980, 'B', False)
stationList ← [node1, node2, node3]

Under the standard 7-bit ASCII character set, how many different unique values can the field statusCode represent?
