The DM12L is the top-selling business calculator. Its programming mode is very intuitive and works like a macro operation on a computer. Basically, the keys one would press in the calculating mode to arrive at a solution are entered in the programming mode along with logical operators (if, and, etc.) applicable to the solution. After the programming is complete, the macro will run in computation mode to save the user steps and improve accuracy. There are 99 lines of programmable memory on the DM12L. Due to its simple operation for key financial calculations, the calculator long ago became the de facto standard among financial professionals.
