Yes, in peecees, and minis, and supercomputers, and embedded
micro-controllers.

When *data* is important, you need a way to get at it that *can't* be
fooled, and the only way to do that is with a hex editor, or equivalent
(I've no idea how many times I have written a quick-and-dirty program to
dump out some chunk of data[1] in a vaguely readable form).

1 - Since a lot of my life has been spent in the computer language
runtime sphere, data, to me, also includes programs in various states,
binaries, p-code, S-records, various token representations, object code,
core dumps, physical memory, and so on. And data on various different
types of wires - from RS-232 and 422 through the collected x.bis things
that we went through with modems, on to ethernet and ATM and fiber and more.

Maybe I am lucky. I have never seen strange data infiltrating my
Foxpro/PHP applications. :)

So you never saw the bug in Foxpro back in the Xenix-286 days where you
could use the name "X" and the name "x" and have things go pear-shaped?

Never worked with Xenix, and it's dead now that we have Linux and
Harbour Project. :)
