An ASCII csave was also the best way to move a program from the real 
Cocos to the MC-10, as that machine had a different token table for 
BASIC keywords, yet it understood the tape data format.  A language 
about halfway between Color BASIC and Extended Color BASIC.  (It had 
the string capabilities of ECB, but not the graphics, IIRC -- haven't 
touched an MC-10 in close to two decades).

The Yen Buddhists are the richest religious sect in the universe.  They
hold that the accumulation of money is a great evil and burden to the
soul.  They therefore, regardless of personal hazard, see it as their
unpleasant duty to acquire as much as possible in order to reduce the
risk to innocent people.           -- Terry Pratchett, _Witches Abroad_
