Well, I guess that answers that.  Probably not too significant, for most
packet io applications.

Please mail me a copy - I haven't seen this one yet.

Sniff.  Oh well.

Great, should be some interesting reading.  I just reread some really
old stuff about AmigaDOS the other day, and it was quite interesting to
see some of the reasons behind some of the "things" AmigaDOS does.

Are there any changes in functionality to the actual dos.library calls
(even some of the strange functions)?  Most importantly, does
Execute("",Input(),NULL) still work to create a subshell in the same
window, and return when the user types "endcli".

What about command lists passed to Execute?
(eg: Execute("emacs T:xxxx\nendcli",Input(),NULL)).

One thing I'd really like to see someday is the original CBM developed
AmigaDOS... Just to see what we missed out on.  It was supposedly object
oriented, which, it occurs to me, was at a time long before "object
oriented" was a common word.
