unicoDe now, so you guys are stuck hearing from me again.

I learned the computer-related meaning of "sentinel" the same way as
everyone else who began programming on microcomputer BASICs in the early
'80s. In the following classic BASIC line:
100 DATA 20, 18, 16, 24, -1
the value -1 is a sentinel, a recognizably invalid data item that
signifies the end of valid data items. The commas that separate the
values are delimiters.
(But, of course, one could always argue that the commas are recognizably
not digits and, as such, signify to the interpreter the end of the
numeric data item. So maybe on a lower level, the commas are sentinels
too. But I wouldn't have called them that.)

Hey, hey, hey. Tex is a Bostonian. We Californians do play fast and
loose with language sometimes, but we had nothing to do with this.
