How can I use: "VarIsNull and VarIsEmpty" in Lazarus

I have the following code from Delphi:

if VarIsNull(ovFolder.Items) or VarIsEmpty(ovFolder.Items)} then
Continue;

In Lazarus this code give me the error: Identifier not found
"VarIsNull" and "VarIsEmpy". The rest of the code from delphi works
fine.

Help me please!!

It works the same as in non-ancient (D6+) versions of Delphi: add
variants  to your uses clause
