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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

:nNo Main Module Prompt
You are attempting to run the program after you have
unloaded the main module. Every program must have a main
module so QuickBASIC knows where to start running the
program. Either
  ■ Use the Load File command from the File menu to
    reload the main module you unloaded. Or,
  ■ Use the Set Main Module command from the Run menu
    to assign the role of "main module" to one of the
    currently loaded modules.
