How to call sysplex data services in 64-bit mode

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:

Table 1. Sysplex data services
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.

Note: Information provided for the 31-bit APIs is also valid for the 64-bit APIs, even though not explicitly mentioned. Exceptions from that rule are indicated where required.
