The List Active Subsystems (QWCLASBS) API retrieves a list of active subsystems. QWCLASBS replaces any existing data. It does not add the new list to an existing one. To retrieve more information about active subsystems, see Retrieve Subsystem Information (QWDRSBSD) API.
The user space that receives the list, and the library in which it is located. The first 10 characters contain the user space name. The second 10 characters contain the library name. You can use these special values for the library name:
| *CURLIB | The job's current library |
| *LIBL | The library list |
The format to use for the list of active subsystems. You can use this format name:
| SBSL0100 | Basic subsystem list. See Format of the Generated List. |
The structure in which to return error information. For the format of the structure, see Error Code Parameter.
The list of active subsystems that the QWCLASBS API returns into the user space consists of:
The user area and generic header are described in User Space Format for List APIs. The remaining items are described in the following sections. For detailed descriptions of the fields in the tables, see Field Descriptions.

| 0 | 0 | CHAR(10) | User space name |
| 10 | A | CHAR(10) | User space library specified |
