The CLI releases control blocks it has acquired in one of two different ways, depending on how the controlling option is set.
The two possible release mechanisms are as follows:
- Return the control block to the free chain
- Dynamically free the control block
The process is described below:
| WHEN the total number of control blocks allocated is . . . | THEN the released control block is . . . |
|---|---|
| less than the installation-specified maximum value | placed on the free chain. |
| anything else | dynamically freemained. |
