I must be greater than or equal to zero and less than or equal to 127.

FORTRAN 90 Interface

Generic:                              ACHAR (I)

Specific:                             The specific interface name is ACHAR.

FORTRAN 77 Interface

Single:                                ACHAR (I)

Description

Routine ACHAR returns the character of the input ASCII value. The input value should be between 0 and 127. If the input value is out of range, the value returned in ACHAR is machine dependent.

Example

This example returns the character of the ASCII value 65.

 

      USE ACHAR_INT

      USE UMACH_INT

 

!     IMPLICIT   NONE

      INTEGER    I, NOUT

!

      CALL UMACH (2, NOUT)

!                                 Get character for ASCII value

!                                 of 65 ('A')

      I = 65

      WRITE (NOUT,99999) I, ACHAR(I)

!

99999 FORMAT (' For the ASCII value of ', I2, ', the character is : ', &

            A1)

      END

Output

 

For the ASCII value of 65, the character is : A
