Feature request: Start script in background

[DennisOSRM]

First of all, thanks a lot for Relaunch64. I wish coding was that comfortable 30 years ago 😁

I have a minor feature request and perhaps it is already possible to do: I'd like to launch a script in the background, s.t. source code can be edited while the compile program runs in Vice. I use this very simple script right now:

/usr/local/bin/acme -v4 --outfile ROUTFILE --format cbm RSOURCEFILE 
/usr/local/opt/vice/bin/x64sc -autostart ROUTFILE

Perhaps this is already possible and I just overlooked things. And if not it would be really great to add it.
