Since this is the third inquiry I've seen about them, I expect that
either 1) I forgot to mention it entirely, or 2) I wasn't clear about
it. So let's do it here. The poop on pipes follows.

As far as I know, there is no PIPE: device on any version of AmigaDOS
sold by C/A.

Ok, you asks, so where did I get one?

Well, I'm running the PIPE: driver that comes on the MetaComCo ToolKit
disk. Goes in as documented, works as documented, and is worth it's
wait in RAM:. There are two other worthwhile things on the disk: the
AUX-CLI driver that lets you hang CLI's off the serial port, and a
dissasembler that works on AmigaDOS commands and library modules.  I'm
currently trying to do a Unix-like pipe() that won't die horrible
deaths on systems without pipe:'s for the mg shell command (among
other things - just to damn busy these days).

There is also a pipe: driver on some of the ToolKit disks distributed
with the beta (and gamma?) versions of 1.2. I've got one, but have
never used it.

	S'aright?
