When I use the code given, it compiles and displays fine. But when I try replacing \everypar with \EveryPar, it halts during compiling with this complaint: "A number should have been here; I inserted '0'. (If you can't figure out why I needed to see a number, look up 'weird error' in the index to The TeXbook.) mtx-context | fatal error: return code: 1
