The CAISSF Installation Process

While installing the CAISSF routines, the system performs the following actions:

The installation of the CAISSF routines into CSA is accomplished through execution of CAIRIM (the CAS9 procedure). A CAIRIM initialization routine, CAS9INIT, loads the CAISSF routines into CSA.
Before executing the CAS9 procedure, add the following CAIRIM input initialization control statement to member CARIMPRM in the YourdeployHLQ.CAW0OPTN data set.
```
PRODUCT(CAIRIM) VERSION(CAS9) INIT(CAS9INIT)
```
Later, when you start the CAS9 procedure, CAIRIM attaches the CAISSF initialization routine. This in turn loads the CAISSF routines into CSA if they are present in the CAS9 STEPLIB or a link‑listed data set.
Note: If you do not use the optional installation of the CAISSF routines into CSA, the first APF‑authorized caller of CAISSF unconditionally causes the CAISSF routines to be loaded into CSA. If you do not use the CAS9 procedure (CAIRIM) to install the CAISSF routines, you lose the ability to delete or refresh the CAISSF routines. If you do not use the optional placement of the CAISSF routines in CSA, the CAS9 procedure (CAIRIM) does not need to be executed.
