Changing variables mid-script

Say I had a script which read:

task.start
while $connect do
task.receive
end
task.stop

Could I make the variable $connect false whilst the script it running
from
an outside source, other than reading from a file?

Yes. You could use a signal handler or DRb, for example. For signals,
put this somewhere before your while loop:

trap “USR1” do
$connect = false
end

Then "kill -USR1 " will cause $connect to become
false.

DRb is more complicated, but exposes a much richer interface.
