Dear Statalist,

When I run a program based on the "Working with tmap" instructions
(, I get the
error message "invalid file specification" following the "tmap"
command.  In an attempt to figure out what was going on, I ran the
exact code (using the same files) suggested in the "Working with tmap"
instructions.  My exact code is copied below.  The files are the same
files used in the Stata example (and are available online).  Still, I
get "invalid file specification" after the tmap line.

I'd very much appreciate any suggestions.
