I've expanded the example from a while ago:

NEWTYPE.foo
  a.w
  b.w
  c.w
End NEWTYPE

DEFTYPE.foo   tsrc    ;create a variable of the new type, means actually malloc()

tsrc\a=10,20,30

*tdst.foo = tsrc    ;grab the address of the memory where our nt variable is 

If *tdst               ;is this a valid address?
  NPrint Hex$(*tdst)

  NPrint *tdst\a
  NPrint *tdst\b
  NPrint *tdst\c
;
;*tdst=0    ;make sure we are not trying to free that later
EndIf


Statement zorg {ntaddr.l}

If ntaddr>0     ;better check all times
  *dummy.foo=ntaddr
  NPrint Hex$(*dummy)

  NPrint *dummy\a
  NPrint *dummy\b
  NPrint *dummy\c

  *dummy=0
EndIf

End Statement


zorg {tsrc.foo}

zorg {*tdst}


MouseWait
End

Please mind this way you are using the variable (type) itself, normally a new one would have been created (copied) inside the Function. This is not the case here, we are passing the address only.
Hope this helps.

*Edit: With a little bit more information about your goals i might have other ideas. The above example is (as it is now) useless, as it could be done by simply declaring the ntype as SHARED inside the Function.
