I can't see from PRM1 p781 how I would do this, as it doesn't seem
to reference the WIMP sprite pool. Should I be using Wimp_SpriteOP
instead - if so, how?

SYS "OS_SpriteOp",25,,"nameofsprite"

That complains 'No memory is reserved for the system sprite area ...',
suggesting that's where it's trying to point. It's the WIMP sprite pool
I want to delete from.

I see, you need to get the address of the area using :-

SYS "Wimp_BaseOfSprites" TO ,rmasprites%
