Well things are never so black and white. You can certainly edit
multiline commands and functions inside GP (enclose them between {  }) 
but there are no easy way to save them between GP session so it is
more convenient to use an external editor.

You can recall a command using the history and a function text using
?myfunction (where myfunction is the name of your function).

You can also use the system() command to launch an editor from inside GP.

Yes, but obviously you can enclose your script in a function, this way
you script will start when the function is executed, rather than when
the script is run. For example:

start()=
{
 \\Your program here 
}

Load it and then run start() when you want to run it.

Cheers,
Bill.
