CallXML 2.0 Development Guide

Home | Frameset Home

This documentation is for CallXML 2, which has been superceded by CallXML 3. The CallXML 2 language is not being updated any longer. CallXML 3, however, has many new features and is actively being enhanced. If you're writing a new CallXML application, you should use CallXML 3. Click here for the CallXML 3.0 documentation.

<assign> element

Assigns the value specified by the attribute value to the variable specified by the attribute var. As shown above, will assign the value "123" to a variable named "ttt". In addition to variables explicitly assigned by the CallXML markup, CallXML browsers may automatically create variables which contain information related to the call / session.

Variable names must start with a letter (A through Z or a through z) and can contain: A through Z, a through z, 0 through 9, and the underscore. Variable names can be 1 to 40 characters in length and are not case sensitive. Variable names beginning with the characters "session." in any case combination are reserved for internal system variables and cannot be created or set by the programmer. They are excluded from submission in a <goto> or a <run>. The same is for variables of the "application." type.
