We give the basic facts about the current state and different generalisations of the problem first studied by Gaspar Monge: given one (!) ODE for two (!) functions
F(x, y, y', z, z') = 0, y = y(x), z = z(x), (1)

is it possible to give its complete parametric solution
x = x(t, u, u', u'', ...),
y = y(t, u, u', u'', ...),
z = z(t, u, u', u'', ...),

where t is a new parameter, and u = u(t) is a new arbitrary function ?
Recently problems of similar form found applications in optimal control ("flat systems of ODEs"). Obviously this problem also deserves attention in the framework of integrable systems.
