Another example would be this:

In my volcano level, I have an animated sprite (emulated particle) that is used on the top of the volcano, a 32 frame animation of a cool fire cloud effect, it looks all cool and magma . I use BMAP* SuperMagma+32.tga; in the script.

But in the next level, which is a snow level, I have no use for the magma sprite, I want to get rid of it from memory, so that I can use a snow avalanche animated sprite. How will I purge the magma sprite from memory?
