Josef-

The pcb file format is a little difficult to interpret and work with.
Presumably your goal is to load data from pcb into some other program. My
suggestion to you would be to write a pcb exporter to a format supported by
that other software rather than try to write software to parse pcb files. I
think this would be easier, and you'd be able to do a more complete job.
I'd be happy to show you how, or help you to do this.

Cheers,
--Chad

I am trying to write a parser for the PCB file format.<br>
<br>
From the file format description (section 8.8 in<br>
<a href=3D"http://pcb.geda-project.org/pcb-cvs/pcb.html#File-Syntax" rel=3D=

me what is the &quot;scope&quot; of the high resolution flagging by square =
brackets.<br>
<br>
For example, given a symbol like this:<br>
<br>
=C2=A0 Symbol[&#39;!&#39; 12]<br>
=C2=A0 (<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 SymbolLine(0 45 0 50 8)<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 SymbolLine(0 10 0 35 8)<br>
=C2=A0 )<br>
<br>
will the &quot;scope&quot; of the high definition squares extend to the chi=
ldren<br>

<br>
