... because Stata's parser is splitting the command line
into tokens. It is crawling along character
by character:
1. following its own rules on legal names, the
colon cannot be part of the macro name;
2. so the "r" of "fvalcur" must be
the last character of that name
and the ":" must be something else;
and
3. a colon is legal at that point.
