A) Multiline scripts can be constructed within a gp session:
    SillyFunc(n)={
        print(n);
        return(5*n);
    }

defines a function that you can use later in your session.

B) if you have built with GNU readline support, then you can modify  
the script within the gp session: just "^P" to get back to the  
function definition (which may appear on one extended line).

Your best bet in all cases, though, is as Bill suggests: use an  
external editor and "\r".

C) If your script is a sequence of executable statements, yes, they  
will all be executed when read.  I think in general, they way most of  
us work, for even the simplest scripts, is to use functions, so they  
just become defined, without themselves being executed.
