Now there's a blast from the past.  I cut my programming teeth on a CTL
Mod 1, in both BASIC and Algol68R.  Although I used a 1906A with both
FORTRAN4 and Algol60, it wasn't until the 2980 came along (to Oxford
where I met those machines) that I did any serious work in Algol68.

I still think Algol68 is the nicest language I ever learned and I
greatly regret that it never caught on in a big way.  Perhaps an effort
could be made to re-popularize it.  If so, the IO library needs to be
dragged out of the 1960's.
