screen crl-a c question

[David Huang]

Dear

 

I just installed the screen from ports in the FreeBSD 7.0

 

after i tried :

 

screen -s A vi txt

 

and tried

 

ctrl-a c

 

I got the message:

 

Cannot exec 'A' : No such file or directory

 

anybody could do me a favor,  I just want to open 2 console by using the screen.

 

 

Thanks
