I have fixed my problem ---

I was running a test program named, ahhh, test.do

It should not cause a problem, but by simply changing the name to a
nonstandard command, everything is ok.

Without worrying about this much more, I assume the problem was that ml
holds the name of the calling program to, for example, testing.do,
everything worked.

Besides saying "Don't do that," does Stata know why this happened?

Otherwise, lesson learned!
