	as single

Thanks for getting back to me,
This is a performance issue.
Changing a character in a FORTRAN string currently requires a call to
_s_cpy.
(Whereas changing a character in an array does not.)
I am looking for similar compiled code for:
      CHARACTER A(6)
      DO I=1,6
        A(I)=CHAR(I)
      ENDDO
and:
      CHARACTER A*6
      DO I=1,6
        A(I:I)=CHAR(I)
      ENDDO
Apart from being orders of magnitude slower, this is not a bug.
I tried to log this with the lowest of priorities.
Regards,
Andy Robb.

Is this a performance issue or a "correctness" issue ?
