I am curious about just what is happening here.

When I do as I'm told, Mathematica shows


in a cell.

When I type $FullVersion in a cell, Mathematica replies

In[1]:= $FullVersion

Out[1]= $FullVersion

Yet if I try  Cell[TextData[ValueBox["$Version"]], "Text"]
Mathematica shows

 Macintosh 3.0


In[4]:= $Version

Out[4]= "Power Macintosh 3.0 (May 6, 1997)"

What does ValueBox do? Where does it get its information about $Version
and $FullVersion?
