• design time editors for variables and functions, that can be loaded and saved in INI file;
• special links of dependences, tracks the changes in related objects;
• more than 200 build in functions;
• enhance error handling;
• full help and demo.

You will feel the Expression parser as a real extention of your favour compiler at runtime.
