#155 on nero problem

[Daniel Volinski]

Hi All,

I'm using Reduce (CSL, rev 6547), 07-Mar2023, on Windows 10.
If I use "on nero" in the attached file, I get "malformed-TeX-input" when all the components are zero.
I think it should print nothing in the case all the components are zero, not "malformed-TeX-input".

Hi,
Thanks for reporting the issue. The message only appears with fancy printing, for example when the graphical interface is used. If you put the following after loading excalc

symbolic procedure indxpri(v,u);
   begin scalar x,y,z;
     y := flatindxl allindk v;
     for each j in mkaindxc(y,if coposp cdr v
                                 then get(car v,'indxsymmetries)
                               else nil) do
       <<x := pair(y,j);
         z := aeval subla(x,v);
         if null(!*nero and (z = 0)) then
         <<maprin list('setq,subla(x,v),z);
         if not !*nat then prin2!* "$";
         terpri!* t>> else maprin " ">>
   end;

does the message disappear? If so I will commit the change so that it will be included in the next snapshot.

Hi Eberhard,
Thank you for the fix.It works, except that I get a message: "local variable u in procedure indxpri not used",
which is true, the u is never used.Thanks again.
