He provided the listing in the original post.
He had one error on .MCALL line, and one on the .TIN line
U on .MCALL, and UQ on .TIN, if I remember right.
I also find it extremely strange that it would not be possible to start
a user defined macro with '.', but if it works without, that's a strong
indication that the dot was the problem.
Or else Will was not actually using a dot, but only something that
looked like one, or something else funny...?
As for listing the macro expansions in the list file, that can be
interesting, but if the symbol is considered undefined, you're not going
to see anything more.
