Integer BASIC's "*** NO END ERR"

[Zorin the Lynx <yakko@zorin.org>]

Ya know, I've always wondered why an END statement was required in 
Integer BASIC programs on the Apple II. And if you didn't put one in, 
you got the "NO END ERR" message.

Why not just exit quietly when the program finished? The "NO END ERR" 
message wasted valuable ROM space, and had no useful function.

Anyone have any insight as to why Woz put this seemingly useless error 
into INTBASIC? Did he just have extra space and wanted to fill it with 
something?
