ICHAR (The GNU Fortran Compiler) (original) (raw)

Synopsis:

RESULT = ICHAR(C [, KIND])

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.

Class:

Elemental function

Arguments:

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

Return value:

The return value is of type INTEGER and of kind KIND. IfKIND 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

Notes:

No intrinsic exists to convert between a numeric value and a formatted character string representation – for instance, given theCHARACTER value '154', obtaining an INTEGER orREAL 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

Standard:

Fortran 77 and later, with KIND argument Fortran 2003 and later
