"A system, method and computer-readable medium support the use of a single operator that allows a comparison of two variables to determine if the two variables point to the same location in memory."
"SUMMARY OF THE INVENTION
[0015] A system, method and computer-readable medium support the use of a single operator that allows a comparison of two variables to determine if the two variables point to different locations in memory, that is, the reverse of the existing "Is" operator in a BASIC programming language or a derivative of BASIC or BASIC-like programming language. In one embodiment of the invention, the memory locations represent objects. The new operator enables a user to determine if the left operand (e.g., a reference type) "is not" the same instance as the reference type listed as the right operand. The use of a single operand for this concept may increase the readability of the programming language. "
