This language’s purpose is to support non-linear functions, such as Y=F(X), so common in the world of micros. Such functions are typically used to represent characteristic curves of valves.
For example: A speed dependent intermittent wiper system will want to use a look-up table to define the time between wipes. Cut-out currents on electric motors can be accurately set using a look-up table to define the typical current at different positions.
