And, if you find that you really do have a problem with such a program that calls an external program (like tmode and dir) then just use the older version of the program which behaves correctly with your program.

Microware's official recommendation was to use external commands just this way, because internal OS structures could change with a future OS revision, but the command line options could be preserved. (This was true even in the OS-9/68K, 9000 days.)

Thus, I used "tmode" in MiniBanners09. And it won't work as intended under NitrOS-9 because of the command change.
