Thanks a lot for you reply.

I got two problems and showed them: tex output and radcan. In fact, these
are new problems which doesn't occur in version 5.9.2. I wrote a code works
well on 5.9.2 about two years ago. Unfortunately, when I tried to run it on
5.13.0 these days, the above two problems occur. Attached is the source file
and one output file (transfered into pdf. on 5.9.2).

So, it must be something changed from 5.9.2 to 5.13, that make the new
problems.
