In case of resistor valuues r150 (r + integer number),
return 150
R2 n1 n2 r150
In case of r23mod return error = 1 and val = 0, so
r23mod may be read as a model, not an instance parameter
R3 n3 n4 r23mod

Add a flag 'alle' (all event nodes) to the plot command (and maybe others).
All event nodes with length greater than 1 are translated to vectors
with a common scale (named step) and are assembled in a new plot
named 'digital'. They may be plotted or otherwise used in a
.control section.
