QuickBASIC is about to save a file and finds one or more
include files that have been loaded into memory but not
saved to disk since they were modified. Either
■ Choose <Yes> to save the modified include files and
then save the program file.
■ Choose <No> to save the program file, but not the
modified include files, if you are still experimenting
with the include file or do not have complete
confidence in it.
■ Choose <Cancel> if you don't want to save any files.
