linenumbering with listings package in latex

Question

I am trying to insert a code snippet with the listingspackage, and want the lines numbered. However I would like only every 5th line and the first to be numbered (numbers beeing(1,5,10,15,...)) according to the manual:

stepnumber=5 

should do the trick, however using my minimal example (see bottom), I get the line numbers 1,6,11,16,...

May be I misinterpreted he manual 8did that once before), however I am clueless.

If a real latex guru is around, there would be something I would like even more, having every linenumber printed however every fifth in bold/ a different style numbers than beeing: 1 2 3 4 5 6 7 8 9 10 11 ... however since this is not in the doku I am sure it requires some deeper latex/listings knowledge.

P.S.: There is one more oddity, eventhough I put "numberfirstline=false" I get the line number 1 ( I get that linenumber as well without setting numberfirstline, which should default to false), it is jsu in there to point out that something is wrong.

I am using miktex for compilation, if that helps.

Thanks in advance.

\documentclass{scrreprt}        %[twoside,headings=openright] %Sourcecode formatting \usepackage{listings}  \lstset{          numbers=left,               % Ort der Zeilennummern          stepnumber=5,               % Abstand zwischen den Zeilennummern                 numberfirstline=false  }  \begin{document} \lstinputlisting{sourcecode/AES/lookupSoftcoded.S} %codefile with 15 lines or so... \end{document}

You can get the desired numbering like this:

\lstset{   numbers=left,   stepnumber=5,       firstnumber=1,   numberfirstline=true }
