>>The scope of a NAME name is Private, so it's generally both practical and OOPish to do things that way.

Jim, I was just illustrating that the scope of whatever "variable" is placed in the NAME clause is treated as private in scope. It is not necessary to declare these NAME clause parameters (they are implicit), unless they're properties. For example

DO FORM etc NAME oSomething && similar to private var, but not declared

or

DO FORM etc NAME thisform.oChild && from TL form-managing method

Whatever is placed after NAME is private in scope...obviously, the second one is more OOPish than the first. The only time I actually use anything other than a form property is for a top-level launch in the main PRG, e.g.,

DO FORM mytoplevel NAME oTopform
READ EVENTS

oTopform is private, but global in nature due to its location in the main PRG. This requires no Public declaration, so might be considered a slight step ahead of an application object in that respect.
