save
Save a set of outputs
General form
save [all | output ...] .save [all | output ...]
Save a set of outputs, discarding the rest. If a node has been mentioned in a save command, it appears in the working plot after a run has completed, or in the rawfile if spice is run in batch mode. If a node is traced or plotted (see below) it is also saved. For backward compatibility, if there are no save commands given, all outputs are saved.
When the keyword "all" appears in the save command, all default values (node voltages and voltage source currents) are saved in addition to any other values listed.
