Integer string to pull

I have a seriese of integers stored in a file in teh second record. I need to pull these Integers to match them with appropriate lines in another file for ex

file a has 4 integers
12 34 45 56

file b has the integers and the sentence they corespond to
12 i like
34 to eat
45 chocolate
46 vanilla
56 cake

how do i get vb to read these integers and write the line so file 3 would read: i like to eat chocolate cake

notice i ignored the vanilla cause it wasnt an integer pulled.

i hope this is clear enough for your help.

All my supervisor told me was that the integers are stored in the secod record of the file.
