conversationID

The system variable SysVar.conversationID stores the conversation ID, which is assigned when an EGL program uses a VGUI record to present a Web page. A related variable is sessionID, which contains an ID that is specific to the Web application server session.

The conversation ID is unchanged when a program in a Web application is invoked by way of a converse statement or by way of a show statement that has a returning clause. A new conversation ID is assigned, however, when the user invokes a program in response to a show statement that has no returning clause.

You can use SysVar.conversationID in these ways:

The characteristics of SysVar.conversationID are as follows:
Primitive type
CHAR
Data length
8 (padded with blanks if the value has less than 8 characters)
