A subroutine does not return a value, but can return many values via its arguments and can only be used as a stand-alone command (using the keyword call ). real function f (x) real, intent (in) :: x integer :: i f = x do i = 1, 10 f = sqrt (f) - 1.0 if (f < 0) then f = -1000. return end if end do end function # The default value is: NO. In a function subprogram, the value of the function then becomes available to the referencing unit. Are defenders behind an arrow slit attackable?
