I may be wrong but with quick tests on FriCAS built on top of GCL (the
packaged FriCAS on Debian based system) and FriCAS built with Clozure
CL or SBCL, the handling of default options at startup and via
.fricas.input are different. Personally my .fricas.input contains
')set message time on', it is not taken into account at startup with
GCL based FriCAS, contrary to the ones with SBCL or Clozure CL. So I
would say it's an issue with FriCAS on top of GCL with startup
options.

Regards,

Greg

PS: I tested packaged FriCAS on Debian-based system (1.3.11). Also
1.3.12 on SBCL or Clozure CL. And a recent version of FriCAS built on
top of recent GCL.
