allowing user interaction in screen caommand

[Eric Smith]

I am mapping as follows:
bindkey "^[[1;5l"  eval 'screen' 'stuff "bin/screen_grab_input.sh^M"'  'other' 
'stuff baz'

I want screen to wait until the script `bin/screen_grab_input.sh' has completed 
before executing the command 'other'.
Is that possible?

$ cat bin/screen_grab_input.sh
read input
echo $input
some_command $input


Thanks
