Using gfun:=Parameters to set the value is deprecated.
Instead do gfun[Parameters]('maxordereqn'=11) .
Why is the default value 3?  Perhaps because in 1994, when gfun
was implemented, computers were much slower and had much less RAM.

When I run Maple, gfun[Parameters] reports that maxordereqn has value
infinity.  It seems this is because I have installed the package
"algolib" from http://algo.inria.fr/libraries/ ... which includes
enhanced versions of the gfun library.

I looked there today to write this reply.  It seems the Algo team at
INRIA closed in 2007. But download of algolib is still possible.
