1. Introduction

Some of the text describing global identifiers and global entities can be
misunderstood.  However, the text is not actually incorrect.
It has been suggested that some examples be added to Annex C.


2. Examples for Annex C

[598:25] C.13 Clause 19 notes : Examples of host association (19.5.1.4),
         heading,
         split into subclauses and add new C.13.1:

   "C.13 Clause 19 notes
    C.13.1 Examples of global identifiers and binding labels (19.2)

    <<Example 1:>>
    {code font}
        MODULE M1
            INTERFACE
                SUBROUTINE S() BIND(C,NAME='X')
                END
            END INTERFACE
        END MODULE
        MODULE M2
            INTERFACE
                SUBROUTINE S() BIND(C,NAME='Y')
                END
            END INTERFACE
        END MODULE
    {end code font, begin new paragraph}
    The name S in each module is a local identifier.
    The two interfaces declare two different external procedures,
    one with the global identifier 'X', the other with the global
    identifier 'Y'.

    <<Example 2:>>
    {code font}
        MODULE M1
            INTERFACE
                SUBROUTINE S1() BIND(C,NAME='X')
                END
            END INTERFACE
        END MODULE
        MODULE M2
            INTERFACE
                SUBROUTINE S2() BIND(C,NAME='X')
                END
            END INTERFACE
        END MODULE
    {end code font, begin new paragraph}
    The names S1 and s2 are local identifiers.
    The interfaces declare the same external procedure, which
    has the global identifier 'X'.
