Re: [fricas-devel] Starting FriCAS not in the $HOME directory

Greetings, and thanks again!

From my reading of the spec GCL's parsing of the pathname-type is
compliant.  It also passes Paul Dietz' test suite.  If this is causing
difficulties it would be great if someone could post the failing lisp
code.

There are advantages to not allowing '.' in pathname-name.

Take care,
