VAL is in the yellow book circa 1980 (bottom of p22), PIM-1 (p158), PIM-2
(p158), PIM-3 (p162), and PIM-4 (p150).  In some versions of the single pass,
type transfer was moved to SYSTEM and called SYSTEM.VAL.

Try K King or P Terry.  They are far superior and much later.  King is a good
reference, Terry a good tutorial.
