8.11.9.39 Char Intrinsic

     Char(I)

Char: CHARACTER*1 function.

I: INTEGER; scalar; INTENT(IN).

Intrinsic groups: (standard FORTRAN 77).

Description:

Returns the character corresponding to the code specified by I, using the system's native character set.

Because the system's native character set is used, the correspondence between character and their codes is not necessarily the same between GNU Fortran implementations.

Note that no intrinsic exists to convert a numerical value to a printable character string. For example, there is no intrinsic that, given an INTEGER or REAL argument with the value `154', returns the CHARACTER result `'154''.

Instead, you can use internal-file I/O to do this kind of conversion. For example:

     INTEGER VALUE
     CHARACTER*10 STRING
     VALUE = 154
     WRITE (STRING, '(I10)'), VALUE
     PRINT *, STRING
     END

The above program, when run, prints:

             154
