FSCALE,[<n1>],[<n2>],[<inc>],[<sx>],[<sy>],[<sz>]

scales the forces belonging to the node set defined by <n1> to <n2> with step <inc>, multiplying the force factors with the scaling factors <sx>, <sy>, <sz>. If one scaling factor has the value 0.0, it will be set to 1.0. If <n1> and <n2> are not specified, they will be set to the last 2 defined nodal forces. The default value for <inc> is 1. This instruction works similarly to the NSCALE instruction from the Node Command group, with the difference that forces are modified.
