	In an assembly language TSR, I switch from the interrupted 
foreground program's Program Segment Prefix (PSP) to the PSP of the TSR 
by calling DOS function 50h.

	Is the default Disk Transfer Area (DTA) *automatically*
switched by DOS to be in the new PSP of the TSR, OR do I have to
explicitly set the DTA address to offset 80h of the TSR's PSP by 
calling DOS function 1Ah?

	Thanks.
