I do not see why you are doing this. If you want to call
'saySpadMsg' appropriate io hook should be enough. For
skipping line numbers setting '$IOindex' to NIL should
be enough.
Well, not so easy. ;-) I could probably do this with the ioHook, but
the Jupyter interface also has numbers for input/output. I use $IOindex to
syncronize FriCAS step numbers with Jupyter numbers. Setting $IOindex to nil
is thus counterproductive.
You mean you read $IOindex?
Yes I do.

===================
(defun ws-fmt (marker)
(|sayMSG| (format nil "--FORMAT:~A:~D" marker boot::|$IOindex|)))
(setf |$ioHook|
(lambda (x &optional args)
(cond
; ((eq x '|startAlgebraOutput|) (ws-fmt "BEG:Algebra"))
; ((eq x '|endOfAlgebraOutput|) (ws-fmt "END:Algebra"))
((eq x '|startPatternMsg|) (ws-fmt "BEG:ERROR"))
((eq x '|endPatternMsg|) (ws-fmt "END:ERROR"))
....
===================
As long as nobody changes it inside a jfricas session, everything works
fine. Do you see a problem with that?
Any other option to read FriCAS' step number?
