s>     b)	What 'handle' do i specify when moving data between conventional
- Conventional memory has handle 0 and segment:offset instead offset.

- Yes.

- I never used it, but read NG Interrupts database carefully.
  Suppose setting: 5,0,0x10000*DataSeg+Offset,Handle,10 moves 5 bytes
  from DataSeg:Offset..Offset+4 to area at addresses 10..14 + starting
  address of block which handle is Handle.
