Summary: Unsigned char in K&R?

	Well, actually they do not mention unsigned char being as there
was no such thing in Version VI or even many Version VII systems.  In
fact the system I am using right now, an Interdata 8/32 with Wollongong
Edition VII does not have either unsigned char or unsigned long.

	What they say is that chars might sign extend and might not depending
on the machine, which is even more confusing.
