Hello,
I tried the 'orbits' program. Here is what happened.
(%i5) loa(%i1) build_info();
Maxima version: 5.19.2
Maxima build date: 13:10 9/20/2009
host type: i686-pc-linux-gnu
lisp-implementation-type: CMU Common Lisp
lisp-implementation-version: 19d Fedora release 5.fc8 (19D)
(%o1)
(%i2) load(dynamics);
(%o2) /usr/local/share/maxima/5.19.2/share/dynamics/dynamics.mac
(%i3) display2d: false;
(%o3) false
(%i4) orbits(x*y*(1-y),.2,100,200,[x,3,4,.01]);
Graph passed to plot2d...
Improper name or value in functional position:

orbits(f=x*(1-y)*y,y0=0.2,n1=100,n2=200,domain=[x,3,4,0.01],options=[])(dynamics.mac
line 367)
-- an error. To debug this try debugmode(true);
Thanks,
