The string literal codice_4 identifies this as a line describing straight-wire geometry. The parameter "ITG", short for "integer tag", is a user-provided number used to identify ("tag") this element. The "NS" parameter defines the number of segments the wire should be divided into during the calculation; using more segments breaks the wire into smaller parts and may produce more accurate results at the cost of increased calculation time. The next six parameters are real numbers that define the "X", "Y" and "Z" locations of the wire's two endpoints. Finally, the "RAD" parameter is the radius of the wire. If this is set to zero, then the next line must be a codice_7 line that includes additional information to define tapering rods.
