With the introduction of the z/Architecture®, applications can run in 64-bit addressing mode. The sysplex data services mentioned above can also be called by 64-bit callers using alternate entry points as described in Table 1:
31-bit API | 64-bit API |
---|---|
ERBDSQRY | ERBDSQ64 |
ERBDSREC | ERBDSR64 |
ERB2XDGS | ERB2XD64 |
ERB3XDRS | ERB3XD64 |
The parameters for the 64-bit API are identical to those for the 31-bit API. The 64-bit APIs may be called with parameters located above or below the 2 GB bar, except the answer area which must be located below the 2 GB bar.
