ICHAR(C)
returns the code for the character in the first character position of C
in the system’s native character set. The correspondence between characters and their codes is not necessarily the same across different GNU Fortran implementations.
Fortran 77 and later, with KIND argument Fortran 2003 and later
Elemental function
RESULT = ICHAR(C [, KIND])
C | Shall be a scalar CHARACTER , with INTENT(IN)
|
KIND | (Optional) An INTEGER initialization expression indicating the kind parameter of the result. |
The return value is of type INTEGER
and of kind KIND. If KIND is absent, the return value is of default integer kind.

No intrinsic exists to convert between a numeric value and a formatted character string representation – for instance, given the CHARACTER
value '154'
, obtaining an INTEGER
or REAL
value with the value 154, or vice versa. Instead, this functionality is provided by internal-file I/O, as in the following example:
