}I am looking at the "crypt(3X)" routines "setkey()" and "encrypt()",
}in SysV Rel 3.2, and it's not clear to me how they're supposed to be
}used.  The manual page says:
}
	I have already received a VERY helpful reply to this from
	Mike Oliver at Pyramid, so no need for more follow-ups.

	Briefly, the 64 character arrays passed to setkey() and
	encrypt() are "encoded" versions of the binary representations
	of the characters; for example, if the first character is
	'A', then 'A' = 0x41 = 01000001 which leads to:

		setargs[0] = 0
		setargs[1] = 1
		setargs[2] = 0

	and so on... based on the manual page, I hadn't figured this
	part of it out, and didn't understand what was supposed to
	go into the argument arrays to setkey() and encrypt().
