How do I control the expansion of macros?  F'rinstance, suppose I wanted to
define the macro \foo to expand to exactly what it did before but also with a
bar on the end?  In pseudolatex, this is what I'd like to say:

  \newcommand{\foo}{foo}                % \foo --> foo
  \renewcommand{\foo}{\expand{\foo}bar} % \foo --> foobar

Several examples and references along these lines would be really appreciated!

Thanks muchly, [Ag] gaynor@topaz.rutgers.edu
