o1 = createobject( "form" )
? type( "o1" )
? type( "o1.Name" )
o1 = .null.
? type( "o1" )
? type( "o1.Name" )

o1 is still type O, but it's no longer an object.

>I'm mostly curious, and totaly new to the Universal Thread, but wouldn't it be better to test TYPE didn't return an "O", like the following?

> *create it if you need it
