Clem,
It figures. I should have known there was a reason for the shorter
lines other than display. Conventions are sticky and there appears
to be a generation gap. I use single spaces between sentences, but
my ancestors used 2... who knows why? :).
You never use a real typewriter. Double-space allows you to edit (physically) the document if need be. This was how I did everything before I had easy computer access.
I went to college with an electric typewriter and all my papers were done on it in the fall of my freshman year (until I got access to UNIX). I did have an CS account for the PDP-10 and they had the XGP, but using it for something like your papers was somewhat frowned upon. However, the UNIX boxes we often bought 'daisy wheel' typewriters that had RS-232C interfaces. Using nroff, I could then do my papers and run it off in the admin's desk at night.
