67 | -- The following two procedures support the use of class-wide pool |

| 70 | -- to the operation of the specific pool, which is achieved by a call | |
| 71 | -- to these procedures. (When the pool type is specific, the back-end | |
| 72 | -- generates a call to the statically identified operation of the type). | |
