Formalization of a general computer storage allocation process is attempted. With a given computer M is associated a fictitious computer M′ essentially identical to M except in respect to possession of unbounded primary storage. Mappings of the total storage set (internal and external) of M into the direct address set of M′ are introduced. A program sequence P for M′ is termed M-admissible (relative to a specific execution time period) if there is a mapping under which P and its effective data referents are all located in the direct address set of M. Storage allocation is considered as a process of establishing for an arbitrary M′ program a sequence of mappings, a decoupling of the program into M-admissible subprograms and a linking set of interludes. An existence proof in terms of a completely interpretive M program as indicated. Some special cases are discussed. Various restrictions on generality of M′ programs are considered under which more practical realization of allocation processes becomes tractable.
