Eve online script help needed, please

[BRaven]

I'm in the planning stages of developing my own mining macro for the game, Eve Online, and being new to this I figured this would be a good place to ask a question.

First off, the problem. While mining smaller asteroids, they will be depleted long before the ship cargo is full (or close to full). Is there a way to code a checking system so that if an asteroid is depleted, the macro will target a new one and continue on?

Thank you for your input.
