Liberty BASIC and Just BASIC by Gordon Sweet M3YXH

In my opinion this is the finest Basic for serious Window programming, and it is often difficult to tell if a program has been produced using this, and not by some more expensive software like Visual Basic, unless you see the files. It does need some 14 support files for distributing programs, amounting to just over 1 Mb even when Zipped. It does not allow access to memory points making it more stable, unless resorting to complex API calls. It is much easier to activate the important Windows Boxes, Buttons etc and unlike BBC4W is supplied with a number of detailed example programs demonstration these, and a comprehensive Help menu, and weekly instruction course. A limited freeware version along with registration details can be found at

The full free version with some of the functions missing including the ability to call API is available from:

There is a very large Yahoo support group for both LB though many of the posts arrive over night from the US etc. Both LB and JB have a number of friendly forums as explained in the software, and also sites providing support including over 140 LB News Letters. Unless you deliberately create say a Text or Graphics window a program makes use of the Mainwindow, which is very similar to QB. This gives beginners a chance to experiment with creating a simple program before embarking on using a proper window.

As you can see from a very simple program below you would normally block the creation of this Mainwindow with nomainwin to avoid a user having to close it. It creates an ASCII based BAS file making it easy to experiment with QB programs etc.

Note the use of ‘ instead of REM below and the way a window is referred to as a #handle like a file. The print #1, of earlier versions has been simplified to #1. Note the trapclose ensuring it can be closed correctly by clicking the top left X the usual way. There are many more complex programs in both LB and JB on my site to download, some using API calls such as to play MP3 and MPEG files, produced with considerable help by others.
