An example of line in file1 is like:



GAGLIARDI 7 GILBERTO TREZZANO - DG 30450 3TECH 3TECH 3TECH


All the lines are of this form.
Column 2 is interesting for me.

file2 might contain in one line only a number let's say 7:
- then do not output the line,
otherwise if 7 does not exist in file2
- then output the line (in a file).


At this moment both files are some .xls containing the same columns.
