Invoking DFSMSdss with the application interface

This topic documents General-Use Programming Interface and Associated Guidance Information.

You can invoke DFSMSdss from an application program by using the application interface. This allows you, for example, to gather statistical or auditing information and to specify control variables.

The application interface allows you to:

Fully utilize the invocation capabilities of DFSMSdss when the ATTACH, LINK, or CALL system macro is specified in your application program.
Optionally, specify a list of parameters to be used by DFSMSdss during the processing caused by that invocation.
Optionally, interact with DFSMSdss during processing of user installation options after the installation options exit has been called.
Optionally, interact with DFSMSdss during the processing at convenient points where input/output (I/O) operations are being performed.

Note: DFSMSdss runs as an authorized problem program (nonsupervisor state); any program invoking DFSMSdss must also be authorized and in non-supervisor state.
