Bill,  Okay that works.
Newbie question: why?  I thought I was specifying the incoming data type.
Thanks for the more extensive response earlier; although at this stage "commit" makes me laugh :)
I will try github.

Raymond,

Sorry for the delayed response. Perhaps you have already discovered
the solution.

The line:

   factor_test(x::XDP , y::LIST(NCP))  ==

should actually read:

   factor_test(x , y)  ==

If anybody is running the ncpoly/non-commuting code:
While familiarizing myself with the coding and theory, I have run into a

I have attached the changed files and the problem code is in (?)
test.input
The function factor_test() stalls on the "map()" line; whereas when I do the
same things manually

#map(rank,f_12)
for i in 1..n repeat m:=m*(fct_12(i)::XDP)

works fine.

In particular
-- Factor test

factor_test : (XDP,LIST(NCP))-> BOOLEAN
factor_test(x::XDP , y::LIST(NCP))  ==
  m:=1::XDP;
  n:=#map(rank,y)
  for i in 1..n repeat m:=m*(y(i)::XDP)
  test(x = m)

Which was supposed to automate the checking in the prior last line of
test.input

test(p_12 :: XDP = fct_12(1)::XDP * fct_12(2)::XDP)

to allow variable problem sizes
like so

factor_test(p_12::XDP,fct_12::LIST(NCP))
