Slightly reworked example, which I hope is a bit easier to grasp:
program RecursiveInterface
call c(b2) ! b2's argument a2 has an integer argument,
! but c expects a routine like b1 with an argument a1
! with real argument
contains
subroutine a1(x)
real :: x
end subroutine
subroutine a2(i)
integer :: i
end subroutine
!!!!!!!!!!!!!!!
subroutine b1(f)
procedure(a1) :: f
end subroutine
subroutine b2(f)
procedure(a2) :: f
end subroutine
!!!!!!!!!!!!!!!
subroutine c(f)
procedure(b1) :: f
end subroutine e
end
