ENTRY

 Designates an alternate entry point at which execution of a
 subprogram can start.  It is not executable and must precede any
 CONTAINS statement (if any) within the subprogram.  Statement
 format:

    ENTRY nam [([p[,p]...])] [RESULT (r-name)]]

    nam     Is a symbolic name for the entry point.  The name 
            must be unique among all global names in the program.  
            In a function subprogram, the data type defined for 
            or implied by the name and the data type of the
            function must be consistent within the following groups:  

            Group 1: Type default integer, default real, double 
                     precision real, default complex, double complex,
                     or default logical
            Group 2: REAL(KIND=16) and COMPLEX(KIND=16) 
            Group 3: Type default character 

            If the data type is character, the length of the string 
            must be the same in both the entry and the function.

    p       Is a dummy argument or an alternate return argument 
            (designated by a *).  The arguments must agree in order, 
            number, and type with the actual arguments of the 
            statement invoking the entry point.  The arguments need 
            not agree in name, order, number, or type with the dummy 
            arguments in the SUBROUTINE or FUNCTION statement for the 
            subprogram.  You must use only the dummy arguments 
            defined in the ENTRY statement.

    r-name  Is the name of a function result.  This name must not be 
            the same as the name of the entry point, or the name of 
            any other function or function result.  This parameter 
            can only be specified for function subprograms.

 The ENTRY statement is not executable and can appear within a
 function or subroutine program after the FUNCTION or SUBROUTINE
 statement.  Execution of a subprogram referred to by an entry name
 begins with the first executable statement after the ENTRY
 statement.

 An ENTRY statement must not appear in a CASE, DO, IF, FORALL, or
 WHERE construct or a nonblock DO loop.
