Patent Images

1. A method for programming a computer system including means for displaying images to control at least one of a virtual instrument and an instrument, the method comprising the steps of:

  • displaying on the screen at least one first function-icon that references at least one first control means for controlling at least one first function;

    displaying on the screen at least one iteration-icon that references iteration control means for controlling multiple iterations of data flow;

    displaying on the screen at least one first input variable-icon that references at least one first input variable;

    displaying on the screen at least one first output variable-icon that references at least one first output variable andassembling on the screen a first acyclic data flow diagram including the at least one first function-icon and the at least one iteration-icon and the at least one first input variable-icon and the at least one first output variable-icon, such that the diagram displays a first procedure for producing at least one value for the at least one first output variable-icon from at least one value for the at least one first input variable-icon, and such that the at least one iteration-icon in the diagram indicates multiple iterations of the at least one first function in the course of the first procedure.
