I want to define macros that end a group, doing a few cleanup chores in
the process --- for example, a \beginvcenter \endvcenter pair to center
text vertically in a page.

I would like to find a way to either:
1) Include a closing brace `}' as part of the macro substitution
    or
2) Figure out how to properly use \begingroup & \endgroup to achieve the
same end.

I have defined a macro \vcenter{ *TEXT* } that will vertically 
center the argument text within the brackets as follows:

\long\def\page{\vbox to\vsize \relax}
\long\def\vcenter#1{\page{\vfil #1 \vfil}}


What I want to do is define two macros \beginvcenter & \endvcenter
which allow me to say:

\beginvcenter
   *TEXT*
\endvcenter

and I don't know how.
