THIS FILE DESCRIBES THE LATEST REGISTERED RELEASE OF LIBERTY BASIC
FOR MICROSOFT WINDOWS!!!
Liberty BASIC can be registered on Compuserve's Shareware Registration
service! This makes it easy to pay the registration fee of $35. Just
type GO SWREG to register, and use Liberty BASIC's ID code 120. The
$35 will be added to your Compuserve billing, and Shoptalk Systems will
send you your registered copy.
The unregistered version is available as LB09A.ZIP.
Liberty BASIC is the first Shareware Windows BASIC that lets you write
real Windows programs, not just character mode programs in a Windows
window!
With Liberty BASIC, you don't need to know anything about how Microsoft
Windows works, so writing programs in this popular environment is now
within the reach of absolutely anyone who has only a rudimentary
knowledge of BASIC.
Liberty BASIC has easy to use, built in window objects. There is a window
object for graphics, one for text, and one is a spreadsheet for performing
data entry.
Text labeled and now BITMAPPED buttons can be added to these windows as
desired, and pull down menus can also be added. Many sample button
bitmaps included, and you can create your own with Windows Paint!
NEW!! Listboxes and comboboxes can be added to your windows!
The color graphics window does turtle graphics and will draw lines,
boxes, circles, ellipses, and pie slices. Any of these figures can be
filled or unfilled. Mouse events can be trapped. A simple drawing
application is included! Graphics are drawn in segments, which can
be individually manipulated.
The text window is great for freeform data entry. A Rolodex application
is included as an illustration of its use.
The spreadsheet is great for forms and tabular entry. A graphing program
illustrates how useful it is.
User defined dialog boxes are supported.
Several kinds of default pop-up dialog boxes are provided for input,
notification, confirmation, and file selection.
A powerful visual debugger is included. This powerful tool makes learning
to program easy and fun by letting you watch each line execute and see
each variable change value as your program runs. Experienced programmers
will especially appreciate this facility.
