Sorry, in transcribing this from my TeX machine
to my e-mail machine, I introduced two errors :
it should have read :
> \documentclass {article}
> \begin {document}
> \def \noescape #1{}
> \edef \fileone {\expandafter \expandafter \expandafter \noescape
> \expandafter \string \csname file_one\endcsname}
> \include \fileone
> \end {document}
