What do you really want to do? Do you want some user interaction (please 
insert blabla) or do you want to have a script which works like a *nix 
CLI program (working with args, read from stdin)

It waits for EOF. Try pressing CTRL+D after you've entered the second value.

Or see this example:

$ echo "4 5.67" | octave --eval '[a,b]=scanf("%d %f", "C")'
a =  4
b =  5.6700
