Are notes (apparently written by DMR):
            Random stuff from my directory.  Most probable dates: 1972.
            pig.b is an interesting artifact:  it is a B program
            that echoes what you type in Pig latin.  (Incidentally,
            there is a translation of this program into C, dated 1978,
            in a subdirectory that still spins on a disk attached to
            the Unix machine where I get my mail.)

This jiggled a nerve in my brain, that FINALLY connected.

The TMG manual in the Multics System-Programmer's Manual by Robert
R. Fenichel and M. D. Mcilroy, pub. April 17, 1967 has a sample TMG
program to translate english to Pig Latin.


    It appears (in translation) as a test to a port of PDP-11 TMG:

I haven't yet compared pig.b to the program in the TMG manual.
