* The following two defines are used to convert the storage identifier

|
* (storage_ID) into a byte pointer. This enables the host to use
|
|
* whatever means it likes for storing this data. The Expanded Memory
|
|
* Manager code always uses USEBLOCK to access the pointer to the
|
|
* data storage area and always uses FORGETBLOCK when it is finished.
|
|
* FORGETBLOCK is provided for systems like the MAC II that may wish to
|
|
* allocate a block, lock it before use and unlock it when finished.
