The Fall of FoxPro
FoxPro, short for FoxPro for DOS, was introduced in 1984. It quickly gained popularity due to its ease of use and powerful database capabilities. By the 1990s, FoxPro had evolved into FoxPro for Windows, a language that was ahead of its time. It allowed developers to create sophisticated database applications with relatively simple code, making it a favorite among small to medium-sized businesses.
The decline of FoxPro began in the early 2000s as Microsoft shifted its focus. The company decided to discontinue FoxPro in 2007, citing a lack of demand and the rise of more modern development tools. This decision was met with disappointment by many developers who had built entire businesses around FoxPro. The language was no longer supported, and the future looked bleak.
For those who had invested heavily in FoxPro, the discontinuation was a hard blow. They faced the daunting task of migrating their applications to a new platform, a process that could be time-consuming and expensive. The community of FoxPro developers felt a sense of loss, as if a once-great tool had been forgotten.
The Revival of FoxPro
Despite the odds, the FoxPro community refused to let their beloved language die. They banded together to create a new version of FoxPro, one that would carry on the legacy of the original. This effort resulted in the creation of FoxScript, a modernized version of FoxPro that aims to preserve the best features of the original while adding new capabilities.
FoxScript is not just a rehash of the old FoxPro; it is a language that has been refined and improved for the modern era. It supports modern programming paradigms, such as object-oriented programming, and includes new features that make it more powerful and flexible. Perhaps most importantly, FoxScript is open-source, ensuring that it will continue to evolve and improve with the contributions of the community.
The revival of FoxPro is a testament to the power of open-source and community-driven development. It shows that even when a language is discontinued by its original creators, it can find a new life through the efforts of passionate developers.

Examples of FoxScript in Action
To give you a better understanding of how FoxScript is used, let's look at a couple of examples:
Example 1: Simple Database Application
Here's a simple example of a FoxScript script that creates a new database and adds a table:
// Create a new database
dbCreate("myDatabase.dbf")
// Add a table to the database
dbAddTable("myTable", "id INT, name VARCHAR(50), age INT")
// Add some records to the table
dbAddRecord("myTable", "id=1, name='John Doe', age=30")
dbAddRecord("myTable", "id=2, name='Jane Smith', age=25")
This script creates a new database file called myDatabase.dbf and adds a table called myTable with three columns: id, name, and age. It then adds two records to the table.
Example 2: Object-Oriented Programming
Here's an example of how you can use object-oriented programming in FoxScript to create a simple class:
// Define a class
class Person
// Properties
property name
property age
// Constructor
constructor(name, age)
this.name = name
this.age = age
end constructor
// Methods
method sayHello()
return "Hello, my name is " + this.name + " and I am " + this.age + " years old."
end method
end class
// Create an instance of the class
local person = Person("Alice", 28)
// Call a method on the instance
? person.sayHello()
This script defines a class called Person with two properties: name and age. It also includes a constructor to initialize these properties and a method called sayHello that returns a greeting. The script then creates an instance of the Person class and calls the sayHello method, printing the greeting to the console.
The Future of FoxScript
FoxScript is still a relatively new language, but it has already made a significant impact on the development community. The future looks bright for FoxScript, as the community continues to grow and the language evolves. Here are some of the trends and developments that we can expect to see in the future:
