Sirs Probably these are FAQs but I am new in this newsgroup and I have not
been able to solve them. I use Mathematica 3.0:  (i) I need to convert a long
integer number in List format.	For example if I had the number 123456 I need
to convert it into {1,2,3,4,5,6}:  Is it possible with an instruction?	And, 
(ii) I need to delete from a List A the common elements with other List B: 
for example if A = {1,2,3,4} and B = {1,2} I need to delete by an instruction
the elements 1, 2 of List B from List A to obtain List C = {3,4}.  I am
working with integers with 10.000 digits or more so you can appreciate how
helpful for me it would be to solve these questions.  Thanks in advance.
