Dear Berend,Thankyou very much for your reply. I actually wanted to inserts each row value of A in f[1] anf f[2], with column 1 value in f[1] and column 2 values in f[2]. Once that been done, i should have in the end, 124 vaues of x[1] for column 1 and 124 for column 2.I hope i am clear this time.Thanks for your help.Eliza
