Abstract

A method for representing data types in a graphical program executed by a computer system. The method stores a plurality of executable function icons, scheduling function icons, and data types. A graphical program or data flow diagram is assembled in response to user input utilizing icons which correspond to the respective executable functions, scheduling functions, and data types which are interconnected by arcs or wires on the screen. The wires have different thicknesses, patterns and/or colors to represent the different data types of data being transported on each wire between nodes. The different data types include numerics, booleans, strings, characters, arrays, and structures, among others.
