Ralph, I cannot solve your problem, but observe that there are two
warnings (I always use -ww):
warning: number register `3bot' not defined
warning: macro `T&' not defined
You need a .nr 3bot 0 and .if !d T& .ds T&
before .TS
The best I could do was replace your 3bot line by the two
lines
T}
\^:3,141.59
which would put the number in a more conventional place, vertically
centred.
Also rather than using cat -s why not put the following at the end:
.br
.pl \n[nl]u
