Gee, I wish I had thought of this when I *wanted* to do this.
(I was experimenting with how long it takes to seek down
different directory levels; how much overhead is there in
sticking another level of directories?)  So, I used EMACS to
create a script for me.  Of course, having REXX at the time
would have made it a one-liner . . .

Nope, you spell it G\"odel in non-published stuff.

Thanks for the article!  In response, I give you one from me:
The easiest way to lock up a CLI is to type:

*

It tries to load standard input as an executable!  (You can
usually get out of it after a while, though . . .)

Or this one:  Manx's memcpy() routine is broken if you compile
with long ints; it's only good for memory areas < 64K; the code
looks like:

	bra	.in
.loop
	move.b	(a0)+,(a1)+
.in
	dbra	d0,.loop

when it should look like this:

	bra	.in
.loop2
	swap	d0
.loop
	move.b	(a0)+,(a1)+
.in
	dbra	d0,.loop
	swap	d0
	dbra	d0,.loop2

I can't remember if it checks the direction of the copy first.  Jim,
you out there?

And there's more.  Why doesn't `WaitForChar()' return before the delay
if the user hits ^\ (the EOF sequence?)  And, despite what Peck's
book says, the second parameter is in microseconds, so don't give it
a value less than 20000!

And then there's the raging SetSignal() controversy . . .
