result = ICHAR (c [, kind])

c

(Input) Must be of type character of length 1.

kind

(Input; optional) Must be a scalar integer constant expression.

Results

The result type is integer. If kind is present, the kind parameter of the result is that specified by kind; otherwise, the kind parameter of the result is that of default integer.

The result value is the position of c in the processor's character set. c is in the range zero to n - 1, where n is the number of characters in the character set.

For any characters C and D (capable of representation in the processor), C .LE. D is true only if ICHAR(C) .LE. ICHAR(D) is true, and C .EQ. D is true only if ICHAR(C) .EQ. ICHAR(D) is true.
