I realize my files should be "clean" of control characters and ConTexT 
should (maybe) not be stripping those characters. Then again, they serve 
no purpose in the document. So...


My question: Isn't some more resilience sensible so commands don't 
break? Or error messages?


a formfeed is acting like a newline

\catcode\tabasciicode   \spacecatcode
\catcode\endoflineasciicode \endoflinecatcode
\catcode\formfeedasciicode  \endoflinecatcode
\catcode\spaceasciicode \spacecatcode

cheers and thanks for any thoughts.

I'm not sure if the FF makes it through the mail. A hex editor 
will/would show it in front of the \page (sheer coincidence)
