Boban,
When there is a relation there is an active order in child and you skip based on that order. If you hit the last record within that relation and skip 1 in child you get next record in that order and it might be the record related with next record in parent. However you can limit the got top,bottom,skip to work only on parent related childs. To do that as you move in parent set key to parentkey in child. ie:

Clear All
use customer
use orders in 0 order tag cust_id
set relation to cust_id into orders
locate for cust_id='FRANK' && Move to FRANK in parent
set key to customer.cust_id in orders
go bottom in orders
? orders.cust_id, orders.order_id
go top in orders
? 'Listing for '+customer.cust_id
Do while !Eof('orders')
  ? orders.cust_id, orders.order_id
  Skip 1 in orders
enddo
Set Key To '' in orders
locate for cust_id='BONAP'
set key to customer.cust_id in orders
? 'Listing for '+customer.cust_id
Do while !Eof('orders')
  ? orders.cust_id, orders.order_id
  Skip 1 in orders
enddo
