[R] step-wise and prediction

I would like to know how to use the function step with "for" in order 
to predict.
Id est:

Let M , A, B ,C be vectors of length 15

for(i in 1:5)



and then I would like to compute the predicted value : M* of M, using 
the predictors selected by the function step.
For example if i=1 and step gives us the model M~A,
then in the "for", I want to compute M* by the means of A[11], and 
compare this value to the real value M[11] and so on.

Merci d'avance ,
