| Parameter description : |
| ----------------------- |
| The SCSA is a shared memory area that is used by basis components |
| such as system log, trace, and so on. |
| Depending on the operating system, the SCSA is either created |
| as an independent shared memory area, or as area no. 5 in |
| the SAP IPC interface. |
| If the SCSA is created directly in the operating system, the |
| indicator key can have a numerical or text value. |
| This parameter is for text keys (for example, for OS/2). By default |
| it contains the instance number, so that different instances do |
| not mix up their SCSAs. |
