Subject: When you AddResource, does the Handle now point to a resource?

I am writing a program which installs resources into files. Suppose
I have the following code:

procedure InstallResource;
var
   MyHandle  : Handle;
begin
   MyHandle^^ := {Whatever data to be put in the resource}
   AddResource (MyHandle, rsrcType, rsrcID, rsrcName);
{...etc....}
end;

As I understand it, I use DisposHandle to get rid of one of
my own handles, but I use ReleaseResource to get rid of a
resource.  Assuming that I have written my code as above,
should I now say "DisposHandle(MyHandle)" or "ReleaseResource(MyHandle)"?
If I want to stop treating it as a resource, should I
DetachResource it, or is it already not a resource?

If it is a resource, do I have to explicitly call UpdateResFile
(or WriteResource) before releasing it, or does calling ReleaseResource
automatically write it out?

Thank you!
