Char: @code{CHARACTER*1} function.

@noindent
Intrinsic groups: (standard FORTRAN 77).

@noindent
Description:

Returns the character corresponding to the
code specified by @var{I}, using the system's
native character set.

Because the system's native character set is used,
the correspondence between character and their codes
is not necessarily the same between GNU Fortran
implementations.

Note that no intrinsic exists to convert a numerical
value to a printable character string.
For example, there is no intrinsic that, given
an @code{INTEGER} or @code{REAL} argument with the
value @samp{154}, returns the @code{CHARACTER}
result @samp{'154'}.

Instead, you can use internal-file I/O to do this kind
of conversion.
For example:

@smallexample
INTEGER VALUE
CHARACTER*10 STRING
VALUE = 154
WRITE (STRING, '(I10)'), VALUE
PRINT *, STRING
END
@end smallexample

The above program, when run, prints:

@smallexample
        154
@end smallexample

@noindent

@noindent
Description:

Returns a @code{COMPLEX} value that has @samp{Real} and @samp{Imag} as its
real and imaginary parts, respectively.

If @var{Real} and @var{Imag} are the same type, and that type is not
@code{INTEGER}, no data conversion is performed, and the type of
the resulting value has the same kind value as the types
of @var{Real} and @var{Imag}.

If @var{Real} and @var{Imag} are not the same type, the usual type-promotion
rules are applied to both, converting either or both to the
appropriate @code{REAL} type.
The type of the resulting value has the same kind value as the
type to which both @var{Real} and @var{Imag} were converted, in this case.

If @var{Real} and @var{Imag} are both @code{INTEGER}, they are both converted
to @code{REAL(KIND=1)}, and the result of the @code{COMPLEX()}
invocation is type @code{COMPLEX(KIND=1)}.

@emph{Note:} The way to do this in standard Fortran 90
is too hairy to describe here, but it is important to
note that @samp{CMPLX(D1,D2)} returns a @code{COMPLEX(KIND=1)}
result even if @samp{D1} and @samp{D2} are type @code{REAL(KIND=2)}.
Hence the availability of @code{COMPLEX()} in GNU Fortran.
