Abstract
The subject disclosure pertains to systems and methods for supporting null capabilities for general purpose programming languages. Low level, runtime support for a nullable type is provided to ensure consistency and coherency. An execution component restricts support of the nullable type to programming language types that lack a null capability. The execution component may also provide support for conversion between the nullable type and a reference type.
