<source> - <source>, AVGS (<source>)}
<source> := {C1, C2, C35, C45}
<max_points> :=

<max_sweeps> := 1 to 1000
Note 1: Parameters are grouped in pairs. The first one names the
variable to be modified and the second one gives the new value to
be assigned. Pairs may be given in any order and may be restricted
to the variables to be changed.
Note 2: The pair SWEEPS,<max..sweeps> applies only when aver-
aging (AVGS) has been chosen. Otherwise it is ignored.
