The great variety of LabVIEW Boolean and numeric controls/indicators, together with the wealth of programming structures and functions, make LabVIEW an excellent tool to visualize and demonstrate many of the fundamental concepts. The PAL architecture consists of two main components: a logic plane and output logic macrocells. Use of font styles (italic, bold, underline) is generally consis-tent.
