I have twos lists I want to compare with one another and delete the
cases where the elements in list1 match list2. For example:
list1={21,41,61,71,81} list2={71,73,75,77,79,81} I want the new list3
to read: list3={21,41,61} It seems to me that the following should
work: list3=DeleteCases[list1,list2] Any thoughts? Thanks Shawn
