Function definition: (Copy & paste into FileMaker's Edit Custom Function window)
The ZapValues function removes from ListA any values which are found in ListB, where ListA and ListB are carriage-return separated text lists.
This provides the logical inverse of FileMaker 7's built-in FilterValues( ) function.

Thank you! I have tried 4 of these functions here to date, and this is the only one that handled properly when value being removed was at start of list twice.
ZapValues ( "a¶a¶b¶c¶a" ; "a" ) does return "b¶c"

Here is the function without a Return at the end, The function name has been changed to 'RemoveVales';
IsEmpty ( ListA ); Let( $repRemoveValues = ""; "");
value = LeftValues(ListA; IsEmpty(FilterValues(LeftValues(ListA; 1); ListB)));
value_trim= Substitute(value;¶; "");
$repRemoveValues = If( not IsEmpty(value); $repRemoveValues + 1; $repRemoveValues);
cr = If($repRemoveValues > 1 and not IsEmpty(value_trim); ¶; "")];
RemoveValues(RightValues(ListA; ValueCount(ListA) - 1); ListB)
