looping newline
I am running Sage 5.1 under Windows 7 using the Virtual Box image.
When I enter a gp program with a newline it goes into a loop.
This works:
%gp
lucas(p) ={my(u,q); u=4; q=1<<p - 1;for(k=3,p, u = (sqr(u)-2) % q);u == 0;}
lucas(5)
But this does not:
%gp
lucas(p) ={
my(u,q);
u=4;
q=1<<p - 1;
for(k=3,p, u = (sqr(u)-2) % q);
u == 0;
}
lucas(5)
Can you tell me what I need to do so that I can enter a program on multiple lines?
