This problem has already been fixed.  The fixed sources, as well as 
executeables for both the original and fixed versions, are available
from Pete Galvin's archive.  Do an anonymous FTP to r20.utexas.edu,
cd to <cc.galvin.public>, and get nansis.asm.  The executeables are
there too, if you want them.  Beware, however, that r20 is a tenex/twenex
machine, and may mangle binaries when transferring them to non-tenex/twenex
systems.   Get around this by setting tenex mode on in FTP, if you need
to.


Hopefully helpfully,

Brent
