SVCCODE

The SVCCODE statement specifies the user SVC number used by CA Spool. The CA Spool SVC is designed so it can run as a normal type-4 user SVC routine. The system administrator responsible for the MVS system must decide which unused Type 4 SVC number to use.

During startup, CA Spool verifies if the specified SVC number in the SVC table points to a valid SVC routine. If the SVC table entry corresponding to the specified SVC number is not in use, CA Spool dynamically loads the SVC routine module into the CSA and updates the SVC table entry to point to it.

Note the following:

• If both the ESRCODE and SVCCODE statements are specified, the ESRCODE definition is used and the SVCCODE definition is ignored.
• During startup CA Spool verifies if the specified SVC number in the SVC table points to a valid CA Spool SVC routine.
• If the SVC table entry corresponding to the specified SVC number is not in use, CA Spool dynamically loads the SVC routine module into the CSA and updates the SVC table entry to point to it.
• If an installation wants to pre-load the CA Spool SVC routine into the PLPA during IPL, the supplied ESFSVC module must be renamed to the SVC module name matching the specified SVC number and made accessible using LPALSTxx or MLPA. For example, if SVCCODE=241 is specified, then the corresponding CA Spool SVC module name must be IGC0024A.

ESRCODE

The CA Spool SVC is designed to use the extended SVC-router (ESR) support. This means that the CA Spool SVC does not need to occupy an SVC number by itself. ESR is called (SVC 109) with a routing code in register 15, indicating the module to be given control.

Note the following:

• If both the ESRCODE and SVCCODE statements are specified, the ESRCODE definition is used and the SVCCODE definition is ignored.
• During startup CA Spool verifies if the specified ESR number in the ESR table points to a valid CA Spool SVC routine.
• If the ESR table entry corresponding to the specified ESR number is not in use, CA Spool dynamically loads the SVC routine module into the CSA and updates the ESR table entry to point to it.
• If an installation wants to pre-load the CA Spool SVC routine into the PLPA during IPL, the supplied ESFSVC module must be renamed to the SVC module name matching the specified ESR number and made accessible using LPALSTxx or MLPA. For example, if ESRCODE=241 is specified, then the corresponding CA Spool SVC module name must be IGX00241.
