I don't know about your first question concerning user input (you could
use breakpoints like "Error("please assign a value to x")", but I don't
know how safe that is).
About saving your work: You can use an external editor like emacs or
Notepad to type your functions, save them to a file like myfunc.g, and
That allows you to keep the function over several GAP-sessions, and the
editing is also more comfortable.
If you have already written some function func in GAP, you can save it by
gap> PrintTo("myfunc.g", "func := ", func, ";\n");
This overwrites the previous contents of myfunc.g; use AppendTo if that's
not what you want.
