Example: generate form (reentrant) z/OS DFSMS Macro Instructions for Data Sets SC23-6852-02 |
|
In this example, the generate form of GENCB is used to create a
default request parameter list (RPL) in a reentrant environment.
The macro expansion equates LEN1 to the length of the parameter
list, as follows:
The parameter list is built in the area acquired by the GETMAIN macro and pointed to by register 2. This list is used by VSAM to build the RPL. VSAM returns the RPL address in register 1 and the RPL length in register 0. If the WAREA and LENGTH parameters are used, the RPL is built at the WAREA address. |
