Did you use:

?

If a is very large, and there are no other references to
the same sequence, this statement will be extremely fast.
Euphoria will simply update the length of a,
without copying any elements or allocating/deallocating any space.

I think you need to give us some more context to this problem.
What are you trying to do? Why do you have to do it so often?
What is the typical length of a?
