[GotToBTru]: I
[GotToBTru]: ve been looking at a document we have been sending to a customer for years now
[MidLifeXis]: We don't, at least in this case ;-)
[GotToBTru]: and it includes a reference number that I didnt recognize
[GotToBTru]: I had to dig into the code to find out where it came from .. and it makes no sense
[GotToBTru]: so I emailed my contact asking if we could just stop sending it .. I'm afraid she is going to ask "what is that anyway?"
[MidLifeXis]: heh.
[MidLifeXis]: Most likely it is a code that some undocumented system, hidden behind layers of IT, deep in the bowels of the building under the machine room floor, reads that code to keep a presence switch from going off. :-b
