FoxPro Scan command
  FoxPro has a specialist type of loop specifically for processing data in tables. The 
  Scan loop steps through the a recordset and executes the 
  statements in the loop body for each record. Its simplest form is equivalent to a
  While loop:
 
  
   Go Top
   Do While Not Eof()
       
       Skip
            
    
     EndDo
 
  It is however more flexible than a While loop because
  the Scan can accept any of the
  
    scope
  clauses which will select which records are to be processed. As an example, this
  Scan loop will only process those records which are after
  the current position of the record pointer and which have the cost field greater than 
  1,000:
 
  Scan Rest For cost > 1000
