The sysVar system variable holds miscellaneous values that do not fit in other libraries.
For core sysVar variables, see EGL library sysLib.
For COBOL programs, the primary purpose of the session ID and conversation ID is to synchronize information between tiers 2 and 3.
The qualifier sysVar can precede the name of each EGL system variable listed in the following table:
| System variable | Description |
|---|---|
| conversationID | Stores the conversation ID that is assigned when an EGL program uses a VGUI record to present a web page. |
| sessionID considerations for web transactions | Contains an ID that is specific to the web application server session. |
