Even if you don't have a one-one
relationship you can make it generally
applicable...just don't join directly in
non one-one cases. Instead....lets say you are making your
selection in layer B on field "select_fld". Make "new_select_fld" in layer
A of same type/length. Tag the entire
layer A with values of B. Then make your selection set on
layer A with this new field
and NOT layer B. Then you can make the set visible as Armando noted and
Tag just the set of A.
This way you only need to create one new field
on layer A and no new fields on B (unless you are using multiple fields to
select then add more). Should work on all cases regardless of type
(numeric/non-numeric).

Subject: Re: [Maptitude] tagging using a selection set from SOURCE
You have a layer A and a layer B. There si a selection set S in layer
B. You watn to tag just the elements in A that are within the elements
in S, and would like to keep all the other elements in A untagged-
If this si what you want do as follows here is a potentail solution ( I
am using you want to tag using a numeric field, if the field is a string
the procedure below needs to be modified).
1) Create a new fiedl (my_new_field) on B, and fill all records with 0
2) on the dataview, display only the S set, and fill the field
created on 1 it iwht 1
3) Create a new field in B using this formula my_new_field *
tagging field
4) Tag your field in A usign the formual you created on 3.
The elements in A overlapping the elements in S will be tagged
accrdogingly. All other records will be tagged with a 0
Just my first thought. But I have the impression it sounds cumbersome so
it is quite possible there might be a simpler solution.
As per Dave�s suggestion, I have the impression he is assuming there is
a one to one relatiobnship between source and target, so I am not sure
his method would be generally applicable
Good luck
