To start the WLM application, you use the TSO/E REXX exec IWMARIN0. The exec concatenates (via LIBDEF and ALTLIB), the following libraries necessary to run the application:
| Library | Content |
|---|---|
| SYS1.SBLSCLI0 | Application REXX code |
| SYS1.SBLSKEL0 | Application skeletons |
| SYS1.SBLSPNL0 | Application panels |
| SYS1.SBLSTBL0 | Application keylists and commands |
| SYS1.SBLSMSG0 | Application messages |
The exec also allocates some MVS™ partitioned data sets for the service definition using TSO ALLOCATE, and then invokes the WLM panels. If you have different data set conventions for your IPCS/WLM libraries, or if you use storage managed data sets, you should use the WLM application exits IWMAREX1 and IWMAREX2. For more information about how to code the exits, see Customizing the WLM ISPF application.
