Why are you using "LOCATE" after "$CONSOLE:ONLY"?
If the console is 25 lines, the "LOCATE 27" which is the last cursor placement makes the screen roll. Either you make the "CMD.EXE" window longer up and down, or you take away the "$CONSOLE:ONLY" and add "WIDTH 80, 30" near the top of your program or something else.
EDIT: The screenshot indicates the program is working as expected. But it might benefit from a "CLS" first of all. Trying to treat the console like "SCREEN 0" is tricky on Windows.
