I can sure make use of this too. I am currently doing this with DDE in
win95, but i'd prefer to do it in msdos, but at the moment, i don't have the
time to write this code. In win95, if the DDE fails, it just fails, no
problems,,,  if it succeeds, then something happens. The DDE handles can be
registered, unregistered, changed, etc,, and new instances run and killed.
Maybe linux offers a better way of doing this,,, sigh, yet another porting
to another OS. Also, in Mirc, i can load a script and run it, and unload it,
no problem, while it is running. It's a terribly limiting "OS", it's not an
OS, it's an irc client,, and i am hoping i can easily do the same things in
Euphoria. One other thing i like in Mirc is the ability to build a var while
it's running:

set -u5 %someothervarname thisisatest
set %Somevar. [ $+ [ %someothervarname ] ] any var, regardless of type.

now %Somevar.thisisatest equals: any var, regardless of type.
and in 5 seconds, %someothervarname is erased, set to $null, deleted, etc

and:
unset %Somevar.*
will set to $null, erase all variables with names beginning with
'%Somevar.".

I figure i can pull it off using sequences in Eu. Mirc is incredibly slow
and memory limiting in storing variables. Has anyone already done this? An
easier timer interface, like mirc has, would be nice also. 

Kat,
still exploring for that perfect programming language.
