No time to reduce this one, filing it so it doesn't get lost:
module cyclic
implicit none
contains
function ouch(x,y)
implicit character(len(ouch)) (x)
implicit character(len(x)+1) (y)
implicit character(len(y)-1) (o)
intent(in) x,y
character(len(y)-1) ouch
integer i
do i = 1, len(ouch)
ouch(i:i) = achar(ieor(iachar(x(i:i)),iachar(y(i:i))))
end do
end function ouch
end module cyclic
program test
use cyclic
implicit none
write(*,*) ouch('YOW!',' ')
end program test
