The fact that the data type is pointer has no relationship to the field being multiple.  Type and frequency are different ideas. So a multiple pointer field has the potential to have several instances of a pointer value.  But that pointer value can only point to one file record and not a sub-file record.  Don't confuse where the pointer resides, in a sub-file in this case, with what it is pointing to.

Cameron pointed out (pun unavoidable...  ;-) that a variable pointer datatype can point to sub-files.  But I concur.  Don't go there.... ;-)

Greg,

Thanks for your answer.  I am confused, though, about
the POINTER issue.  FIELD^DID says that the multiple
field is of type POINTER.  Yet you say that pointers
can not point to subfiles.  Are you sure on that
point?

Thanks
Kevin

Furthermore, if I ask for the TYPE for this field

I get back "POINTER"

Is there any way to tell if the pointer is to a
separate file, or whether it is a subfile?

      
Pointers can only point to files, not subfiles.
