ATM no such thing. It is a bit tricky but some day it will probably
irritate me enough to write a better command line handling. Basically
one needs to switch to different mode on incomplete input. Easy
to say, but devil is in details...

You can put '_' at the end of line so that FriCAS will treat next
line as continuation of the current one. Note that since '_'
joins lines to form long logical line usual pile rules do not
work and you need to use parentheses and semicolons to delimit
statemets.

Some people use Emacs mode.
