Making a type global?

Is it possible to make a type global? How do I do it? Is there some reason they're not automatically global like an array? I'm passing one of my types from function to function and it seems simpler to just make it global. Can it be done?

Global m.myType

Type myType
  Field X%
  Field Y%
End Type

Try this:

Type myType
   Field X%
   Field Y%
End Type
m.myType = new myType
Global m.myType

I'm not sure, but you may be able to combine the last two lines, putting Global on the type as you create a new one.
