I got SCANDISK to work with the EDR kernel. I used [interc3](https://pushbx.org/ecm/download/interc3.zip) to monitor the DOS calls performed by SCANDISK and compared them between MS-DOS 7.1 and the EDR kernel....

Source indicates that HISTORY=ON,256 might do the trick (setting history to 256 bytes). The valid range seems to be 128-4096 bytes. But did not test it yet.
``` ; ; This function modifies the History buffer support provided by ; DR DOS the defaults are History OFF, 512 byte buffers, ; Insert ON, Search OFF, Matching OFF....
Anything to do here apart from documenting this stuff?
Improvement suggestion could be summarized as "do not store same command line multiple times in history"?
