Re: Just to mudddy the waters a trifle ...
I've sometimes heard the hash referred to as a waffle.
And in Univac-speak, the ! is sometimes referred to as a bang (as in: "We ended up having to dollar-bang the 1100-80) and sometimes as a shriek (as in: "To list all lines using the pine editor type pee-shriek").
Though I have heard someone (from TSB) speak of "Pee Bang*", I've never heard anyone say "Dollar-Shriek".
