Hi Waldek,

Many thanks for this quick response and fix. Just tested on official FriCAS
and the 2 problems you mentioned previously gone away.

The .fricas.input file is still not "read" but for my mid-term work it is
not a big problem, my startup file is just displaying computation times and
augmenting line length of output to 110. Maybe this is related to my Kali
distribution on WSL2, I don't know.

The )read command is to blame on my settings:

(1) -> )sys pws

   >> System error:
   INTERNAL-SIMPLE-ERROR: The assertion !posix_spawnp(&pid, *p1,
&file_actions, &attr, (void *)p1, environ) on line 65 of o/unixsys.c in
function vsystem failed: No such file or directory

(1) -> )sys pwd
/home/greg
(1) -> )sys ls -l .fricas.input
-rw-r--r-- 1 greg greg 35 Feb 11 09:42 .fricas.input
(1) -> )read .fricas.input

   The file .fricas.input is needed but does not exist.

BTW great improvements have been done for gcl-2.7.1, thanks to you and
Camm, it's a very good thing for me since I plan to code a wrapper in
Common Lisp using my C wrapper to Julia compatible with GCL. I did one for
Axiom in the past, a coding LISP game for me containing only "and", "or
"and "not" keywords (no loops or conditionals). A direct wrapper to Fortran
BLAS in fact. Now I have to look at documentation changes for the GCL-2.7
series FFI.
