My response would be very similar to yours:

FOR mycount = 1 TO 10
    lcCmd = ;
      Field(m.mycount) ;
      + " WITH 1501002 FOR " ;
      + Field(m.mycount) ;
      + " = 1301002 "
    REPLACE &lcCmd. IN Table1
NEXT

The help says ALL means all records in the table. The FOR is limiting the records, so you're not doing all. ALL is therefore not required.
