I think that

if type("MyVar") = "O" and !isnull(MyVar)

or

if vartype(MyVar) = "O" and !isnull(MyVar)

is what you need.

...Y soy feliz, bien feliz, asi lo grito;
Mira, que el mundo sepa, que se sepa:
Soy feliz....                       

...And I'm happy, quite happy, so do I yell it;
Look, so the world knows it, so be known:
I'm happy...
