The assistant can be used to create new variables as well as to edit and delete existing ones. In the assistant area "Document variables", all variables created so far in a document are displayed with their name, value [content] and description. Only when the changes are saved via the "Save" button are all changes made finally adopted and confirmed by a green highlighted message to the left of the "Save" button. When the administration of the variables is complete, the assistant can be exited with the "Close" button. |
