Marks the end of a program unit or procedure.
Syntax
- keyword
is one of the keywords BLOCK DATA,
FUNCTION, MODULE,
PROGRAM, or SUBROUTINE.
When the END
statement is used for an internal procedure or module procedure,
the FUNCTION
or SUBROUTINE
keyword is required.
- name
is the name given to the program unit. If name
is specified, keyword must also be specified.
Description
The END
statement is the last statement of a program unit (that is, a main
program, function, subroutine, module, or block data subprogram),
an internal procedure, or a module procedure. It is the only statement
that is required within a program unit.
Examples
The following example illustrates the use of the END
statement to indicate the end of a main program. Notice that, even
though the main program unit is given a name, the END PROGRAM
statement does not require it:
PROGRAM main_prog
...
END PROGRAM |
In the next example, the END
statement marks the end of an internal function and must therefore
specify the keyword FUNCTION.
However, it is not required that the name, get_args,
be also specified:
FUNCTION get_args (arg1, arg2)
...
END FUNCTION get_args |
The following example uses the END
statement to indicate the end of a block data subprogram. Because
the END statement
specifies the program unit name, it must also specify the keyword
BLOCK DATA:
BLOCK DATA main_data
...
END BLOCK DATA main_data |
