InterSystems: The power behind what matters   

Used to compare two object reference variables.
result = object1 Is object2
The Is operator syntax has these parts:
result Any numeric variable.
object1 Any object name.
object2 Any object name.
If object1 and object2 both refer to the same object, result is True; if they do not, result is False. Two variables can be made to refer to the same object in several ways:
In the following example, A has been set to refer to the same object as B:
Set A = B
The following example makes A and B refer to the same object as C:
Set A = C
Set B = C
