Is there a simple way (without having to check all the datatypes) to get the equivalent empty value for a variable. For example

FOO(12) ------------> 0
FOO("abcd") --------> ""
FOO(DATE()) --------> { }
FOO(DATETIME()) ----> { :}

etc.

I can write FOO if I need to. Just wondering if there is already a feature in the language.

Thanks......Rich
