Wrote code since before you were born (1968). Went to an AMR conference in 1992 at which Hasso Plattner introduced R/3 to the US market and heard him say "Vee hope ze Uzers hef fun viz zis softvare". Switched to ABAP and had fun every day since. Probably up to a couple of hundred thousand lines by now. Taught it to anyone who would listen.
