Yes, I've read this help page. But as far as I understand, this only
allows to generated a "paged" file name, but not to include the value of
a variable in the file name. Foo is a dummy name. It is only the
numerical part of the name what variates in the samples above. I guess
it won't be difficult to get Foo from values in a vector once I
understand how the whole thing does work.
