I'm a LiveCode newbie, but I'd want to minimise the time spent asking
"is it time for me yet" for each of those commands.
I'd probably try to put the commands into a list ordered on the frame
number. Your insert is a little trickier here, because you need to
preserve the order of the frame number.
Each time through the loop, you look at the first command on the list,
and if the current frame is less you know no actions are due and ignore
it, if it matches, remove it from the list and perform the action, and
then check the next item on the list.
Does that make sense? Is there a better way to handle such things in
