Or maybe it was a 7-bit code with a parity bit and they're counting it
as 8-bit.

Recognizing that 42 graphics — 26 alphabetics, 10 numerics, and 6 specials (period, comma, slash, asterisk, minus sign, and dollar sign) — were common to all trains/chains, an edict was issued that only these 42 graphics could be used on reports.

I found a pre-ASCII standard proposal at
https://archive.org/details/enf-ascii-1961-09 that refers to
"MIL-STD-188A". Googling *that* finds stuff referring to Fieldata, so
that's probably what it's referring to. Fieldata does have a "Special"
control character immediately before DEL. And now that I check again,
the WPS page does say "For all intents and purposes "FIELDATA" today
refers to the character code. It, or a minor variant, is sometimes
called the "DoD standard 8-bit code".
