Important Notice
The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.
Cannot set Tabs
When you have a file open that contains a previously set
tab stop, it cannot be changed with the Tab Stops option
from the Display command. Save your file, then use the
New command to clear the QBasic View window.  Use the
Display command to set the tab stop, then reopen your file.
