Interesting. I have received several responses to this both on the
net and by mail, and some say that CS is necessary, and some say it 
isn't. My reading of POP is that CS is not necessary when storing a
fixed value into a fullword, as Brian Eliot points out, _even if another
task modifies COUNTER between the L 1,COUNTER and the CS 1,0,COUNTER_.
It will just cause the loop to be gone through again. I guess it goes
to show that lots of other people misunderstand CS as well as the 
author of this program. (The reason for not "leaving it alone" is that
zeroing a word by CS is actually quite expensive, btw.)

Thanks for your comments.
