The listing command is used to generate a listing of the current circuit.
listing [l[ogical]] [p[hysical]] [d[eck]] [e[xpand]] [n[ocontinue]]The command will print a listing of the current circuit to the standard output. The arguments control the format of the listing. A logical listing is one in which comments are removed and continuation lines are appended to the end of the continued line. A physical listing is one in which comments and continuation lines are preserved. A deck listing is a physical listing without line numbers, so as to be acceptable to the circuit parser -- it recreates the input file verbatim. The last option, expand, is orthogonal to the previous three -- it requests that the circuit be printed after subcircuit expansion. Note that only in an expanded listing are error messages associated with particular lines visible. When using deck and expand, by default long lines are broken into continuation lines. If the nocontinue option is also given, this will not be done. This option is ignored in other cases.
If no argument is given, logical is understood.
