Preamble:I worked on Lizard since 8 years. Lizard differs significantly from other script languages, as you can see in the features below. Lizard is very similar to the mathematical and scientific program Mathematica. Lizard should make it possible to carry out calculations, data analysis and much more with a small script without much code. At the moment I am only providing you with the Lizard.dll, its include file as well as some examples and a detailed documentation on Lizard. The publication of the source code is planned and since I don't use a WinAPI, nothing should prevent a compilation on Linux! Please test Lizard at this early stage and give me feedback on the current features. I would also like to explicitly thank the following people who probably didn't even know that they helped me: Helle (ASM optimization), CSHW89 (idea and division algorithm) Download:Lizard  Symbolic computation script language (Version 0.3.80012) Contains the Lizard.dll (x64 and x86), the Lizard.pbi, some examples for the integration in Pure Basic and a detailed documentation for Lizard with many examples. Lizard  Documentation (Documentation only, just for viewing) Features of Lizard: Full support of symbolic expression.
 Support of arbitrary size integers.
 Support of rational and complex numbers.
 Full unicode character string and binary string support as well as unicode collation algorithm.
 Support of polymorphic or anonymous functions.
 Powerfull pattern matching engine for assignments and replacements.
 Support of named parameters in functions.
 High flexibility in work with subparts of strings, lists or general expressions.
 Numerous conversion functions, supporting different number formats and string formats under consideration of endianness and digit base.
Details:In Lizard everything, really everything, is an expression consisting of a head and any number of arguments. That means also object types themselves, e.g. lists or wellknown keywords such as If, And etc. are again just expressions and can also be used again as such. This makes Lizard very flexible and powerful, but on the deep level it is also slower than usual script languages, in which these things are clearly separated and differentiated. Here are some examples of the features (many more in the documentation):Code: In(1) := {2^100, 8/12, 1/4.0, (2.0)^0.4} Out(1) = {1267650600228229401496703205376, 2/3, 0.25, 0.40775+1.25493*I} Code: In(2) := {3*x  2*x, a && True && b, Sin(Pi/6)} Out(2) = {x, a && b, 1/2} Code: In(3) := Sort( {3, 2, 1, 0, 4}, Abs(#1) <= Abs(#2) & ) Out(3) = {0, 1, 2, 3, 4} Code: In(4) := Select( {1, 2, 3, 4, y, 2.2}, #^2 < 6 & ) Out(4) = {1, 2, 2.2} Code: In(5) := Replace( a+b+c+d, a+d > x ) Out(5) = b + c + x Code: In(6) := {a,b,c,d,e}[2..2] Out(6) = {b, c, d} Code: In(7) := "Hello World!"[1..1..1] Out(7) = "!dlroW olleH" Code: In(8) := Table(i^2, {i, 3, 3} ) Out(8) = {9, 4, 1, 0, 1, 4, 9} Code: In(9) := ToString('\0a\x03» ¬', BinaryFormat>"UTF16", Endianness>1) Out(9) = "aλ€" Code: In(10) := Sort({"NINO", "Nina", "Nino", "Ninu", "Niño"}) Out(10) = {"Nina", "Nino", "NINO", "Niño", "Ninu"}
Have fun during testing. ChangeLog 0.3.80012: x86 support!, small bugfixes, two more examples for pure basic implementation, new Lizardfunctions: Floor, Ceil, Trunc, Order
 0.3.80002: First publication
