Variables can be used any number of times and at any place in a project. Their first and fore-
most purpose is the exchange of information between the different elements of a Frame or also

Usually, the values of Variables change during the course of a DCO-Script in the OScAR-Pro-
TT Operator-Tool.

Example
You can, for example, create a Variable to memorize in a Frame which announcements were
used by a subscriber for a broadcast. In a OScAR-Pro command template (see Section 5.8.7,
"OScAR-Pro command templates"), the Variable could be used at the beginning of a broadcast
so that the currently assigned value, namely the ID of the selected announcement, is trans-
ferred to the OScAR-Pro-TT Operator-Tool.
