Initial Comment: Hi, Thank you for the quick solution of my previous bug. What I am reporting now seems a bug to me, otherwise it is a very strange feature, in my humble opinion. I write two consecutive loops (not nested), say, for i : 0 thru 4 do display( i ), for j : 0 thru 4 do display( j ); and Maxima executes the second loop first. This is counterintuitive to me. If it is intended, I would beg for a rationale.

I;m pretty sure you did not intend that. Probably you want (%i1) (foo, bar); or (%i1) block (foo, bar); either of which evaluates the items within parentheses one by one. (The plain parentheses (...) is like block(...) except that (...) cannot have a list of local variables.) Hope this helps. Closing this report as rejected since it's not a bug.

The problem is that (mul2 1 (list '(%signum simp) (neg y))) doesn't send the signum expression through simplifya. In this code, if (mminpus y) and (mminusp (neg y)) are both true, the code will infinitely loop. Here is another (untested) fix. As a bonus, it does signum(signum(x)) > signum(x). It uses the applyreflectionrule scheme instead of mminusp. I don't see the point of the (mnump y) check in the original code (speed maybe)  csign should take care of this. I also cut the eqtest stuff. Maybe that's not goodI don't know.

I guess if whichever simplification functions are carried out return an expression with a different operator, then maybe start over? I guess the problem to watch out for is endless looping.

Then the plotting functions will put the Gnuplot output file there.
