Re: How to do ... appendum

Jasper:

I'm not really clear on what your problem is, but if you are running into a
maximum number of allowable variables, simply eliminate the H1, H2, H3 ...
definitions. For example, rather than:

> H1:=(C-A)*(Ref(C,-1)-A)
> +(Ref(C,-1)-A)*(Ref(C,-2)-A)
> +(Ref(C,-2)-A)*(Ref(C,-3)-A)
> ;
> r1:=H1/H0;

the following will reduce the number of variables used by nearly half:

> r1:= ((C-A)*(Ref(C,-1)-A)
> +(Ref(C,-1)-A)*(Ref(C,-2)-A)
> +(Ref(C,-2)-A)*(Ref(C,-3)-A)) / H0;
