Hi John,
you can't. But you can evaluate your equations on some interesting
points.
If you have solved
sol=NDSolve[deqn,{x[t],y[t],z[t]},{t,0,100}]
you can insert the solution into the equations:
insdeqn=deqn /. sol;
And evaluate the equations along the time interval
test=Table[insdeqn /. t->tt, {tt,0,100,0.5}]
this should give you the information you need.
Hope that helps
Jens
