Translation of empty lists

Empty lists (e.g. if no solution is found by Solve) caused a useless error message.

y sin 0 ≡ x y - sin y sin ≡ 21 sys x y 21 sys Solve no result

Recommendation to try an alternative solver

system unknowns parameters Solver

unknowns are variables to solve for, parameters are variables assumed to be known, all arguments must be lists.

Path handling in Draw2D and Draw3D

If the filename is not given, then a temporary directory is used and a unique name is generated. No particular directory setting required in this case

Translation problem with Algsys fixed

While reworking the list translations, algsys interfered with sys, this is now fixed.

Bug report by Radovan:
