What is the advantage of freeing an entire subpool vs. freeing the memory by address?

Also, you can share/transfer subpools with/to different tasks. One more advantage of using different subpools is that you can free up all the storage in any given subpool by only one STORAGE (or FREEMAIN) macro. If you use different subpools for different purposes, you could free up all the storage used for purpose X by doing one FREEMAIN-type macro, whereas if you used subpool 0 for all storage, then you would need multiple FREEMAIN-type macros, each of which frees up only one piece of storage in that subpool.
