Hi all,

This is my first post to here.
I have a problem and want your help.

Mathematica 4 did the following calculation with no pleblem,
while Mathematica 5(.2)  cannot do it.

FindRoot[
 (f /.NDSolve[ {D[f[x], {x,1}] - 2 x - a == 0, f[0] == 0}, f, {x, -3, 3} 
][[1]])[2] == 4,
 {a, -10, 10}
              ]

Does anyone know solution or altanative way to do it?
