Return values only contained in ListA

Sample Input:

AntiFilterValues( "1¶2¶3¶4¶1¶"; "1¶3")

Assuming you have archived a list of record ID values for a table:
AntiFilter(OldRecIDlist; newRecIDList)

Sample Output:

2
4

List of deleted records

Description:

Updated 10/13/2008 - now correctly fully matches list item

Another custom function that does the opposite of the built-in FilterValues function. It returns the list of items that are only contained in ListA.

This one has high performance across tens of thousands of records and in my testing, beat performance of some of the compile and calculate list methods.

Deals with recursion limit by using a hardwired multiline calculation, and by dwindling the list.
