due to additional requirements, i have this:

if [[ "$TERM" != vt320 ]]; then
  if ! which screen|grep "no screen"; then
    if screen -ls|head -n3|tail -n2|cut -f2|cut -d. -f2-|grep -q
'^'main'$'; then
      exec screen -r main
      exec screen -S main

the extra "if" is due to my generally having at least one detached
"daemon" screen hanging around. (the TERM test filters out my
blackberry's ssh app. i have enough trouble using it without dealing
with ^A :)

a named version of -D -RR (attach to named screen (power-detaching
others if necessary) if exists, create if not) would be a welcome
alternative: "screen -D -RR main"
