Tusk is a statically typed interpreted programming language, implemented in, and largely similar to, Delphi.

The articles in this topic provide an introduction to the language, starting with a quick example program…

Writeln('Hello, world!');

The above program prints out the message, "Hello, world", and demonstrates a few basic Tusk principles…

• Writeln is a function that prints text.
• Functions are called using parentheses, though as in Delphi, a zero-argument function can be called without parentheses.
• Strings are enclosed in single-quote characters.
• Semi-colons separate adjacent statements.

Tusk does not have a unit concept, and keywords such as unit, program, uses, interface, implementation, initialization, and finalization are not valid (though they are reserved as keywords, primarily for improved Delphi compatibility).
