Hi Chrisantha,
NDSolve gives a list of pure (function without name) functions back. By
a replace rule you can get a named function. E.g.:
fun= y/. NDSolve[{y'[t]==y[t],y[0]==1},y,{t,0,1}][[1]]
we can then get the end value by e.g. by fun[1].
Note, if you have time consuming calculations, the object
NDSolve`StateData may save you some time. See Help "NDSolve" under
"Advanced Documentation".
good success, Daniel
