This article was previously published under Q34761 SUMMARY
Microsoft does not give out any information about undocumented system
features. If calls, flags, or interrupts are undocumented, it is
because they are not supported; we can give NO guarantee that they
will exist in future releases of MS-DOS. If you find out about these
features (through articles or by chance) and begin using them in your
programs, there is a real potential that your application will not
work in future MS-DOS versions.
We strongly advise against using undocumented features for these reasons
and will give out no information about their use.
