-Once you start using braces, there are a number of
-mistakes that you can make.  For example, you can
-leave a brace out, or you can get them out of order
-(Like } xxx { ), or you can get them in illegal places.
-For all of these, neqn tells you "syntax error",
-then tries to say what file and line numbers are
-involved.
-The line numbers are often not exact, but
-they are very close.  When you get such a message,
-print a line or two before and after the line
-numbers named in the syntax error message.
-
-The file "Example" contains a syntax error.
-What line does neqn believe it begins on?
-Type "answer N", where N is the line number.
