Thanks Michael... Hmm, it'll be interesting. The number of lines between 
the refdes=xxx and OrderCode=yyy 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 :)

For now I'll just use grep to locate which .sch files contain the 
specific order code, then hop around the schematic in gschem using 
Attributes->FindSpecificText .

Regards,
Matt.
