> Thanks Michael... Hmm, it'll be interesting. The number of lines =
between the refdes=3Dxxx and OrderCode=3Dyyy lines, varies in number and =
sequence. So outputting via grep would need a blanket number of =
pre-match context and post-match context lines to include. It'd be messy =
:)

Make a file named =93attribs=94 with contents:

device
value
spec
footprint
description
OrderCode

(adjust as needed)

Then do =93gnetlist -g bom -o bom.txt <your schematics>

That will maintain the relationship between refdes and attributes.
