Ferris & Spotter - we use electronic strips where traffic pops up - it's no problem as we have a default flight plan entry screen - when you call it up it opens with the cursor in the callsign field, you type in the callsign and hit the enter key twice and bingo - the FDPS computer creates an "airfiled" VFR plan with a discrete SSR code allocated - once the driver airframe copies that and dials it into his transponder you get a full data block on the screen - takes about 30 seconds all up.
Paper is a pain.
