\begin{description}

\item[{\tt *}] Comment line.
\index{comment line}

\item[{\tt !}] Pass a command to the operating system.

\item[{\tt <}] Batch mode.

\item[{\tt >}] Direct the ``standard output'' to a file.

\item[{\tt Ac}] Performs a small signal AC (frequency domain) analysis.
Sweeps frequency.

\item[{\tt ALArm}] Select points in circuit check against limits.

\item[{\tt ALTer}] Perform analyses in queue.  Changes follow.  (Not
implemented.)

\item[{\tt Build}] Build a new circuit or change an existing one.

\item[{\tt ChDir}] Change current directory.

\item[{\tt CLEAR}] Delete the entire circuit, titles, etc.

\item[{\tt DC}] Performs a nonlinear DC analysis, for determining transfer
characteristics.  Sweeps DC input or component values.

\item[{\tt DELete}] Delete a part, or group of parts.

\item[{\tt DIsto}] SPICE command not implemented.

\item[{\tt EDit}] Edit the circuit description using your editor.

\item[{\tt ENd}] Perform analyses in queue.  New circuit follows.
(Implemented incorrectly.)

\item[{\tt EXIt}] Exits the program.  (Same as quit)

\item[{\tt FANout}] List by node number, the branches that connect to each
node.

\item[{\tt FAult}] Temporarily change a component.

\item[{\tt Fourier}] Transient analysis, with results in
frequency domain.  (Different from SPICE.)

\item[{\tt Generator}] View and set the transient analysis function
generator.

\item[{\tt GET}] Get a circuit from a disk file.  Deletes old one first.

\item[{\tt Help}] Requests advice on error messages, options, command
syntax.

\item[{\tt IC}] Set transient analysis initial conditions.
(Not implemented.)

\item[{\tt INsert}] Insert a node number.  (Make a gap.)

\item[{\tt List}] List the circuit on the console.

\item[{\tt LOg}] Save a record of commands.

\item[{\tt MArk}] Mark this time point, so transient analysis will restart
here.

\item[{\tt MErge}] Get a circuit from disk.  Add it the what is already in
memory.

\item[{\tt Modify}] Change a value, node, etc.  For very simple changes.

\item[{\tt NODeset}] Preset node voltages, to assist convergence.  (Not
implemented.)

\item[{\tt NOIse}] SPICE command not implemented.

\item[{\tt OP}] Performs a nonlinear DC analysis, for determining quiescent
operating conditions.  Sweeps temperature.

\item[{\tt OPTions}] View and set system options.  (Same as set.)

\item[{\tt PAuse}] Wait for key hit, while in batch mode.

\item[{\tt PLot}] Select points in circuit (and their range) to plot.

\item[{\tt Print}] Select which points in the circuit to print as table.

\item[{\tt Quit}] Exits the program.  (Same as exit.)

\item[{\tt SAve}] Save the circuit in a file.

\item[{\tt SENs}] SPICE command not implemented.

\item[{\tt Status}] Display resource usage, etc.

\item[{\tt SWeep}] Sweep a component.  (Loop function.)

\item[{\tt TEmp}] SPICE command not implemented.

\item[{\tt TF}] SPICE command not implemented.

\item[{\tt TItle}] View and create the heading line for printouts and files.

\item[{\tt Transient}] Performs a nonlinear transient (time domain)
analysis.  Sweeps time.

\item[{\tt UNFault}] Undo faults.

\item[{\tt UNMark}] Undo mark.  Release transient start point.

\item[{\tt Width}] Set output width.
