Well, the intent clearly was that "printing" produces a bundle
containing step number and value,
The time this method was invented for FriCAS, the people that invented
jupyter where probably not yet born. The idea of having possibly another
UI for FriCAS was not on the screen. "Saturn" was an in-house product.
and that separationg step number and value should be easy.
Can you do it for all cases? Just two are given below. "Easy" is
something else.
To say the truth it looks somewhat strange that you want to
suppres printing of step number but want its value.
The printing of the step number in the fricas algebra output consumes n
colums of space where n depends on the number of digits of the step
number. If the step number appeared in the beginning of the output, then
perhaps I could parse the output, extract the value, remove the columns
from the fricas output, and use it for jupyter. But it doesn't always
Reading $IOindex is definitely a simpler solution, given that the step
number cannot always be easily removed, see below. And I do not think
that it makes sense to print the step number in the FriCAS output (and
thus waste some output columns if it there is anyway a "Out[step]" in
jupyter, which should, of course agree with what FriCAS thinks the step
number is to make %%(stepnumber) work as expected.
