Multiple database function (MDBF) macros
The macros required to support a system generated with the multiple database function (MDBF) provide
the facility to access resources in a subsystem (SS) other than the
one generated for the user. This cross subsystem access can either
be directed from an SS or subsystem user (SSU) to the BSS or from
the BSS to an SS or SSU. The resources accessed can be one of the
following:
- Program base
- Database
- Fixed file record SS or SSU
- Pool file record SS or SSU
- Global data SS or SSU
- Main storage resident SS data.
| Macro name | Restriction | Description |
|---|---|---|
| CEBIC | System | Change SS or SSU Data Resource ID |
| CROSC | System | Cross SS Access Service |
| LEBIC | System | Load (and index) ECB Resource ID |
| UATBC | General | Request for SSU Attribute Table Reference. |
| Note: The system
macros are described in z/TPF System Services and the general
macros are described in z/TPF General Services.
