You can still express models using traditional LINDO's simple style of model expression in LINGO. Other notable advantages to switching to LINGO are:

1. You can solve nonlinear models also, not just linear.
2. You can use set notation, e.g., use subscripted variables. This is very handy for formulating large models that nevertheless have a simple repetitive structure. No tedious typing of 100's of constraints.
3. Using the global solver, you can find guaranteed global optima to nonconvex nonlinear problems,
          e.g., Max = (x-5)^2;
                   0 <= x; x <= 9;
4. If you want to solve a series of models, e.g., to compute a set of points on an efficient frontier, or to solve a collection of Data Envelopment Analysis models, this is easy to do with the scripting or programming capability in LINGO 10.
5. Ability to automatically extract input data from and return solution data to Excel spreadsheets,
6. Faster and more powerful solvers.

LINDO's simple interface and straightforward model expression style make it easy to learn and use. Traditional Interactive LINDO is appropriate for building and solving moderately sized linear and integer models.
