These instructions are unavailable in VB/WIN 1.0.  Although, several
third party libraries provide them (and you could also write your
own DLL to do this).

>Are they available in the new Visual Basic for DOS?

Yes.

The mouse is automatically available to your programs in VB/DOS.  Similiar
to VB/WIN.

No.  VB/DOS uses far strings, and QB uses near strings.  Generally this 
difference would cause the libraries to be incompatable.

Writing or reading directly to hardware is dangerous under Windows because
you can't be sure what other apps are doing.  Therefore, you should either:
1.  Go thru the Windows API for comm functions (our PSS people will be happy
to explain this ... actually quite easy)
2.  Use a custom control available from several vendor such as MicroHelp
and Crescent (among others)

>Are they available in the new Visual Basic for DOS?
Yes.  Every last language feature that Basic PDS has, incl. INP and OUT
work unmodified in VB/DOS.  Please keep in mind that VB/DOS has the Basic
PDS 7.1 code at its core...we didn't try to emulate QB/PDS, we built on top
of it .. like we did for VB/Win.

Absolutely.  Forms and controls work automatically with a mouse.  You do not
write one byte of code for it.

>

Generally yes but you should call your vendor.  The libs need to work
with Far Strings (virtual all commercial .libs/.qlbs already do).  Your
vendor might also have enhanced versions of your current libs.

No, Visual Basic for Windows does not have direct port access via OUT and
INP. Because it's a Windows application, it must use the Windows API to
access ports.

Yes, OUT and INP are definitely still in there for Visual Basic for MS-DOS.

You bet. That's what event-driven programming is all about. Mouse support
is built-in. All you have to do is program what you want to happen when
a mouse moves, or a button clicks. It's great!

The compiled files will not work by simply plugging them in. You'll have
to recompile the source code. Then everything will work fine.
