variable names and order

write:

 Maxima reorders terms for commutative operators,

(%i1) a=b+c;
(%o1)                              a = c + b

Is it possible to preserve the original order in the underlying
S-expression, so that when I need a LaTeX fragment I get the original
order?  Also, is it possible to influence/change ordering of results?



(%i1) a=b+c;
(%o1) a=c+b
(%i2) a+b+c;
(%o2) c+b+a

(%i3) ordergreat(a,b,c);
(%o3) done

(%i4) a=b+c;
(%o4) a=b+c
(%i5) a+b+c;
(%o5) a+b+c
