Fwd: beginner’s question wi th Maxima

(adding back maxima-discuss)

Glad to hear you fixed the various issues.

Re your *s* macro, there are two problems:

   - *sum* auto-quotes the expression and index arguments.
   - *s *calls *sum* at macro-expansion time

You can use *buildq *-- which is specifically designed for writing macro
bodies -- to substitute the values:

s(i, i_min, i_max, expr) ::= buildq([i,i_min,i_max,expr], sum(expr, i,
i_min, i_max))$
