If you download the file in question and try opening it in gretl
as specified, you get:

"This file is not an 'OLE' file -- it may be too old for gretl to
read." It's some sort of ancient Microsoft format. (Thanks, St
Louis Fed!). The "file" command on Ubuntu 10.04 says:
"INDPRO.xls: CDF V2 Document, corrupt: Cannot read summary info"

Sorry, --rowoffset=XX is not available for plain text files, only
for spreadsheets.

Noted above. Try, for example, stata ".dta" files available via
the web, these should work OK.
