Rules
The END statement is the only required statement in a program unit.
If
a name is specified in an END BLOCK DATA, END
FUNCTION, END MODULE, END
PROGRAM, END SUBROUTINE, 
END
SUBMODULE, or END PROCEDURE
statement,
it must be identical to the name that is specified in the corresponding BLOCK
DATA, FUNCTION, MODULE, PROGRAM, SUBROUTINE, SUBMODULE,
or MODULE PROCEDURE statement.
For an internal
subprogram or module subprogram, you must specify the FUNCTION or SUBROUTINE keyword
on the END statement. In Fortran 2008, you can omit the FUNCTION and SUBROUTINE keywords
on the END statements for internal and module
subprograms. However, you cannot add a function or subroutine name
on the END statement when the FUNCTION or SUBROUTINE keyword
is omitted. For block data program units, external
subprograms, the main program, modules, interface bodies, submodules,
and separate module subprograms, the corresponding keyword is optional.
The END, END
FUNCTION, END PROCEDURE, END
PROGRAM, and END SUBROUTINE statements
are executable statements that can be branched to. In both fixed source
form and Fortran 90 free
source form formats, no other statement can follow the END statement
on the same line. In fixed source form format, you cannot continue
a program unit END statement, nor can a
statement whose initial line appears to be a program unit END statement
be continued.
The END statement of a main program terminates execution of the program. The END statement of a function or subroutine has the same effect as a RETURN statement. An inline comment can appear on the same line as an END statement. Any comment line appearing after an END statement belongs to the next program unit.
