My QBASIC programs do not run under Windows XP. Specifically, LPRINT does nothing.
I have spent a lot of time & effort over the past 15 years programming in QBASIC with lots of useful and profitable programs. I really do not want to start over with Visual Basic unless there is a MIGRATION or CONVERSION or "CHEAT SHEET" comparing code.

As far as I know, QBASIC is a pretty passee language. You might consider upgrading to Visual Basic due to the simplicity to create windows applications, in addition to the fact that it is completely object oriented. Good luck!

What's LPRINTs purpose? Does it swap the lpt ports or something?

In QBASIC, the PRINT statement prints to the screen while LPRINT prints to the printer.

XP will not run 16 bit applications to my knowledge without some type of emulation service running. I dont mean to judge you as a programmer but anyone who has spent so many years programming should have the logic behind programming in general well developed mentally. It is that logic that allows programmers to do what we do. A language is merely the extension and syntax we use to express this mentality. I would highly recommend not remaining binded to one language as it helps widen your horizons as a programmer to experiment in different languages. Good luck and I hope you find something that works for you.

VB is not COMPLETELY OOP.

Polymorphism is not implemented in VB.

To put it bluntly - you are wrong.

Polymorphism in VB.NET

You may have been thinking of an older version of VB, but VB.NET 7.0 (2002) and VB.NET 7.1 (2003) are 100% completely object oriented.

Sorry to break your heart - VB.NET is just as powerful as the next language.

Edit: I have now realized that the posted article is for "registered" readers only. If you want to find more about polymorphism in vb.net, google will give you a good 10,000+ results :-)

To get back on topic, there's a post located here that might be of some help:

I learnt Qbasic when I took my gcse O levels under the University Of London and for IT I had to learn Qbasic.I think Qbasic is very easy and a basic type of langauge matured ppl don'treally need that at all.

I started out using GW-BASIC in 1986 and moved on to QBasic. The transition from QBasic to Visual Basic, in 1997, was painless as the only thing needing to be learned was dealing with forms. I think the transition to VB, which Microsoft offers a free version (control creation edition), should be relatively painless.
