Function 1Ah (26)        Set Disk Transfer Address (DTA)

Sets the Disk Transfer Address (DTA).

On entry:      AH         1Ah
DS:DX      Address of DTA

Returns:       Nothing

                                                                          

Notes:         DOS supplies a default DTA of 128 bytes at offset
80h in the Program Segment Prefix (PSP).

Reserve sufficient buffer area; DOS will detect and
abort disk transfers that would wrap around within
the segment or fall off the end of the current
segment.

This function is used with the FCB Read and FCB
Write file operations. It is also used with the
"Find First" and "Find Next" functions, both Handle
and FCB.
