LINGO allows you to express the entire group of constraints in one concise statement. Taking advantage of sets is the foundation of LINGO's modeling language, the fundamental building block of the program's most powerful capabilities. LINGO even allows you to express common sets implicitly, such as days of the week or months of the year.

The modeling language's similarity to standard mathematical notation makes it very easy to read. Models are easier for the developer to maintain and for colleagues to read and understand.

Using LINGO, the dimensions of your model can be changed without requiring changes to your expression of the problem. For example, suppose you are finding the cheapest way to supply a product from several different warehouses to several different customers. If the number of warehouses or customers change, many modeling packages would require significant changes to the problem's formulation. However, with LINGO, your problem formulation needs no modification. You can simply change the size of your data files and LINGO takes care of the rest.

LINGO's modeling language includes an extensive library of mathematical, probability and financial functions. For more information, see the List of Built-in Functions. You can also create user defined functions for LINGO to use. LINGO accepts generalized expressions including those with parentheses and variables on the right-hand side. LINGO allows you to have meaningful variable names up to 32 characters.
