Think of an OS (execution environment) without process boundaries. 

Consider also (regarding word "program"):

(Programming Terms according to IBM)

    Application program 
        A collection of one or more programs cooperating to achieve 
        particular objectives, such as inventory control or payroll. 

    Environment 
        In Language Environment, normally a reference to the run-time 
        environment of HLLs at the enclave level. 

    Language Environment Terms and Their HLL Equivalents: 

    Routine 
        In Language Environment, refers to either a procedure, 
        function, or subroutine. 

        Equivalent HLL terms: COBOL--program; C/C++--function; 
        PL/I--procedure, BEGIN block. 

    Enclave 
        The enclave defines the scope of HLL semantics. In Language 
        Environment, a collection of routines, one of which is named 
        as the main routine. The enclave contains at least one thread. 

        Equivalent HLL terms: COBOL--run unit, C/C++--program, 
        consisting of a main C function and its subfunctions, 
        PL/I--main procedure and its subroutines, and 
        Fortran--program and its subroutines. 

    Process 
        The highest level of the Language Environment program 
        management model. A process is a collection of resources, 
        both program code and data, and consists of at least one 
        enclave. 

    Thread 
        An execution construct that consists of synchronous 
        invocations and terminations of routines. The thread is 
        the basic run-time path within the Language Environment 
        program management model, and is dispatched by the system 
        with its own run-time stack, instruction counter, and 
        registers. Threads may exist concurrently with other 
        threads.

alexander.
