CON – Spin Language Reference Example:
OBJ Num : "Numbers" PUB SomeRoutine Format := Num#DEC
'Set Format to Number's Decimal constant
Here an object, “Numbers,” is declared as the symbol Num. Later, a method refers to numbers’ DEC constant with Num#DEC. Num is the object reference, # indicates we need to access that object’s constants, and DEC is the constant within the object we need. This feature allows objects to define constants for use with themselves and for parent objects to access those constants freely without interfering with any symbols they created themselves.
