ICHAR(3f)

DESCRIPTION
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.

STANDARD
Fortran 95 and later, with KIND argument Fortran 2003 and later

CLASS
Elemental function

SYNTAX
RESULT = ICHAR(C [, KIND])

ARGUMENTS

C Shall be a scalar CHARACTER, with INTENT(IN) KIND (Optional) An INTEGER initialization expression indicating the kind parameter of the result.

RETURN VALUE
The return value is of type INTEGER and of kind KIND. If KIND is absent, the return value is of default integer kind.

EXAMPLE
          program test_ichar
            integer i
            i = ichar(' ')
          end program test_ichar

SPECIFIC NAMES

Name Argument Return type Standard ICHAR(C) CHARACTER C INTEGER(4) Fortran 77 and later

NOTE
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:
          program read_val
            integer value
            character(len=10) string, string2
            string = '154'

            ! Convert a string to a numeric value
            read (string,'(I10)') value
            print *, value

            ! Convert a value to a formatted string
            write (string2,'(I10)') value
            print *, string2
          end program read_val
