Combine to fields

Question

Hi all,
I would like to know how i can combine two fields into one without leaving a gap in between. for example
VendId
W0031 01
s0051  02
I would  like for the gap in between to disappear and show like this
VendId
W003101
s005102
Below is the query i am working on.
thanks
SELECT DISTINCT (v.vendor || r.addrnum ) "VendId",v.vendor "Vendor Id", v.vnamel "Vendor Name",
                r.aaddr1 address, r.acity city, r.astate state,
                r.azipcode "Zip Code", r.aphone "Phone Number",
                TO_CHAR ((MAX (p.datepur)),
                         'YYYY-MM-DD'
                        ) AS "Plan Purchase Date"
           FROM vendor v, vendaddr r, planhold p
          WHERE v.vendor = r.vendor
            AND p.vendor = r.vendor
            AND (p.datepur >= TO_DATE ('2002-01-01', 'YYYY-MM-DD'))
            AND v.vobsolet = 'N'
       GROUP BY v.vendor,
                r.addrnum,
                v.vnamel,
                r.aaddr1,
                r.acity,
                r.astate,
                r.azipcode,
                r.aphone
       ORDER BY v.vnamel
