\def\vec#1

\def\vec#1

All,

This is fine.

\starttext

\startformula
\left(\matrix{y_1\cr y_2\cr \vdots\cr y_n}\right)=
\left(\matrix{x_1^2\cr x_2^2\cr \vdots\cr x_n^2}\right)
-2\left(\matrix{x_1\cr x_2\cr \vdots\cr x_n}\right)
-\left(\matrix{3\cr 3\cr \vdots\cr 3}\right).
\stopformula
If
\startformula
\vec x =\left(\matrix{x_1\cr x_2\cr \vdots\cr
  x_n}\right)\quad\hbox{and}\quad
\vec y =\left(\matrix{y_1\cr y_2\cr \vdots\cr y_n}\right),
\stopformula

\stoptext

But when I redefine \vec, I get a problem.

\def\vec#1{\bf #1}

\starttext

\startformula
\left(\matrix{y_1\cr y_2\cr \vdots\cr y_n}\right)=
\left(\matrix{x_1^2\cr x_2^2\cr \vdots\cr x_n^2}\right)
-2\left(\matrix{x_1\cr x_2\cr \vdots\cr x_n}\right)
-\left(\matrix{3\cr 3\cr \vdots\cr 3}\right).
\stopformula
If
\startformula
\vec x =\left(\matrix{x_1\cr x_2\cr \vdots\cr
  x_n}\right)\quad\hbox{and}\quad
\vec y =\left(\matrix{y_1\cr y_2\cr \vdots\cr y_n}\right),
\stopformula

\stoptext

I thought \vec in this case should just chew up the very next symbol, but
the bold seems to continue into the display in the second formula.

I'm missing something here. What is it?

Of course! Thanks.
