Here`s an interview with Arthur Whitney whose K I have linked into CoSy
at his BoF session at Linuxworld :
http://media.vcall.com/archive/ram/linux/kxsystems02022000.ram

It`s from Radio Wall Street :

Stability comes from living in it ; most fundamentally having one general
execution environment - the Job - and execution trapping back to a common
execution
stack - state indicator si

Doing it over , I`d do it much more cleanly .

By "too-simple rule" I imagine you mean edge conditions which demand more
complexity to algorithms than expressing the rule for the entire interior .
That`s life .

Back around 1980 Mike Montalbano of IBM when introducing his
"APL Blossom Time" ( see : http://cosy.com/language/APLBlos/APLBlos.htm )
made the comment about JCL the Job Control Language on IBM systems I
never had to deal with . The comment was a line from an old Edgar Guest pulp
poem : " It takes a lot of living to make a house a home . "

CoSy has survived a lot o living .

But , I find each change of hardware brings new quirks , potholes & freezers
in Windows & Bios etc which require cerebellar level learning to stay clear
of .

I have Blue Book transcript with screen images of a talk & demo I gave
at Peter O`Connor`s Lap & Palm top Expo back in `91 which I can send
you for $25 + postage , but that`s a product of a different time , tho
still generally valid .

A number of people have now downloaded CoSy , I think understanding its use
requires some to start asking me questions , letting me know where the
barriers begin .
