What is Liberty Basic?
Liberty Basic is a modern version of the BASIC programming language that was popular in the 1970s and 1980s. BASIC stands for Beginner's All-purpose Symbolic Instruction Code, and it was designed to be a simple and accessible way for beginners to learn how to program. Liberty Basic follows the same principles, but it also adds many features and enhancements that make it suitable for creating modern applications.
A brief history of Liberty Basic
Liberty Basic was created by Carl Gundel in 1992 as a hobby project. He wanted to create a programming language that was similar to the BASIC he used on his Commodore 64 computer, but that could run on Windows. He released the first version of Liberty Basic as a shareware product in 1994, and since then he has continued to develop and improve it. Today, Liberty Basic is one of the most popular BASIC dialects, with thousands of users around the world.

The GUI builder allows you to design and edit windows and controls using a drag-and-drop interface. You can also set various properties and events for each control. The GUI builder will generate the code for your GUI and insert it into your program.
The syntax and commands of Liberty Basic
The syntax of Liberty Basic is similar to other BASIC dialects, but it also has some differences and extensions. Here are some of the basic rules and conventions of Liberty Basic syntax:
Each line of code can contain one or more statements, separated by colons (:).
Each statement can contain one or more expressions, separated by commas (,).
Each expression can contain one or more operands and operators, separated by spaces.
Operands can be constants, variables, functions, or subroutines.
Operators can be arithmetic, relational, logical, or assignment operators.
Constants can be numeric or string literals, enclosed in quotes ("") for strings.
Variables can be numeric or string variables, with optional type suffixes (% for integer, ! for single-precision floating-point, # for double-precision floating-point, $ for string).
Functions can be built-in or user-defined functions, with optional arguments enclosed in parentheses (()).
Subroutines can be built-in or user-defined subroutines, with optional arguments enclosed in parentheses (()).
Comments can be added to the code using an apostrophe (') or REM at the beginning of the line.
Here are some examples of Liberty Basic statements:
'This is a comment REM This is also a comment a = 10 'This is an assignment statement b = a + 5 'This is an arithmetic expression c$ = "Hello" 'This is a string literal d$ = c$ + " World" 'This is a string concatenation print d$ 'This is a built-in subroutine input "Enter your name: ", e$ 'This is another built-in subroutine f = len(e$) 'This is a built-in function g = sqr(f) 'This is another built-in function h = myfunc(g) 'This is a user-defined function mysub h 'This is a user-defined subroutine
The examples and tutorials of Liberty Basic
If you want to learn more about Liberty Basic and how to use it, you can check out the examples and tutorials that are included with the product. You can access them from the IDE by choosing Help > Examples or Help > Tutorials. You can also find them in the folder where you installed Liberty Basic. The examples and tutorials cover various topics and aspects of Liberty Basic programming, such as variables, data types, operators, control structures, loops, arrays, strings, files, graphics, sound, network, database, web, and more. You can run, modify, and experiment with the code to see how it works and what it does.
How to compile and run Liberty Basic programs
When you write and run your Liberty Basic programs from the IDE, they are interpreted by the Liberty Basic engine. This means that they are translated into machine code on the fly as they are executed. This makes it easy and convenient to test and debug your programs, but it also has some drawbacks. For example, interpreted programs are slower than compiled programs, they require the Liberty Basic engine to run, and they are not protected from unauthorized copying or modification.
If you want to make your Liberty Basic programs faster, independent, and secure, you can compile them into standalone executable files that can run on any Windows or Linux computer without requiring the Liberty Basic engine. To do this, you need to use the GLBCC compiler and linker that are included with Liberty Basic.
The GLBCC compiler and linker
The GLBCC compiler and linker are command-line tools that can convert your Liberty Basic source code into executable files. The GLBCC compiler translates your source code into C code, which is then compiled by the GCC compiler into object code. The GLBCC linker then links the object code with the necessary libraries and resources into an executable file.
To use the GLBCC compiler and linker, you need to open a command prompt window and navigate to the folder where you installed Liberty Basic. Then, you need to type the following command: glbcc filename.bas where filename.bas is the name of your Liberty Basic source code file. This will create an executable file with the same name as your source code file, but with the .exe extension. For example, if your source code file is hello.bas, the executable file will be hello.exe. You can also use various options and flags with the GLBCC command to customize the compilation and linking process. For example, you can use the -o option to specify a different name for the executable file, the -s option to strip the debug information from the executable file, or the -v option to display verbose messages during the process. You can see a full list of options and flags by typing glbcc -h in the command prompt window. The executable files and libraries
The executable files created by the GLBCC compiler and linker are standalone files that can run on any Windows or Linux computer without requiring the Liberty Basic engine. However, they still depend on some external libraries and resources that are provided by Liberty Basic. These are:
The lb451.dll file. This is the main library that contains the core functions and features of Liberty Basic. It is located in the folder where you installed Liberty Basic.
The lb451gui.dll file. This is the library that contains the GUI functions and features of Liberty Basic. It is also located in the folder where you installed Liberty Basic.
The lb451res.dll file. This is the library that contains the resources and images used by Liberty Basic. It is also located in the folder where you installed Liberty Basic.
The lb451.ico file. This is the icon file that is used by Liberty Basic programs. It is also located in the folder where you installed Liberty Basic.
If you want to distribute your executable files to other computers, you need to include these files along with them. You can either copy them to the same folder as your executable files, or to a common folder that is accessible by all your executable files. You can also use a tool like Inno Setup or NSIS to create an installer package that will automatically copy these files to the appropriate locations.
The debugging and testing tools
If you encounter any errors or problems with your executable files, you can use some debugging and testing tools that are included with Liberty Basic. These are:
The lbdebug.exe tool. This is a graphical debugger that allows you to inspect and modify the variables, memory, registers, and stack of your executable files. You can also set breakpoints, watchpoints, and tracepoints to control the execution flow of your executable files. You can launch this tool from the IDE by choosing Tools > Debugger or pressing F11 on your keyboard.
The lbtest.exe tool. This is a testing tool that allows you to measure and compare the performance of your executable files. You can also use it to check for memory leaks, buffer overflows, and other potential errors. You can launch this tool from the IDE by choosing Tools > Tester or pressing F12 on your keyboard.
