	I know this isn't strictly the fodder of this newsgroup - it's more a
beginners C sort of thing, but I guess it applies here because under TCC or
whatever I used to mess with memory locations to achieve the effect, and
DJGPP throws me by being protected mode.
	Anyway, I want to know, how, in DJGPP, do you shift every value of a
variable down one in a dimension, ie so that the value at x[n] is written
to x[n+1], the value at x[n+1] to x[n+2], and so on. I could write a
for/next routine type thing, but this would be slow. Is there a way similar
to memcpy ? Like I said, on other compilers because I did not know the
command, I would just mess with the positions in RAM, but that is not
something I can get to work under protected mode.
	Any help would be greatly appreciated, and extra appreciation will go out
to those who e-mail me instead of replying here, where I only come about
once a week. Thanks though for anyone that helps at all!
