When QuickBASIC loaded a multiple-module program, it
could not find one of the modules listed in the .MAK file.
To complete the load process, QuickBASIC created an empty
module to satisfy the .MAK file's module list.
 
When you rerun the program, QuickBASIC lets you
  - Choose <OK> to delete the empty module and the .MAK
    file entry for the module.
  - Choose <Cancel> to cancel this run operation so you
    can either
      - reconcile the .MAK file entry with the module file
        you may have in a different directory, or
      - save the program text you may have just entered into
        the empty module so you can try running it again.
