Revendication 1:
A method of producing a program modelling a physical process for a computer using data flow diagramming, wherein the computer includes a memory which stores a plurality of executable functions and a plurality of data of various types, a display, means for receiving user input, and a data processor, the method characterised by the steps of
assembling, in response to user input, a data flow diagram on the display, the data flow diagram specifying the process and including function-icons corresponding to respective ones of the plurality of executable functions, terminal-icons corresponding to respective ones of the plurality of data types, a structure-icon indicating control flow of the data flow diagram, and arcs interconnecting the function-icons, terminal-icons, and structure-icon; and
generating an executable program in response to the data flow diagram, the executable program including one or more of the executable functions as indicated by the function-icons and interconnected as indicated by the arcs to operate upon data identified by the terminal-icons, the executable program having control flow established as indicated by the structure-icon.
