In this context, linking means that the data desired for the document (i.e., the linked queries or SQL statements) is stored in the database, whereas the particular position is stored in the document. Once a link of ADABAS data has been added to your document, you can actualize the data contents in your document by clicking on a button.
The following three toolbar buttons are provided for linking ADABAS data with a document:
Microsoft Word 
The toolbar buttons have the following meanings, from left to right:
1. Adding Links
When adding links, QueryPlus is automatically informed about the name of the document as well as the position within the document at which the link is to be added. Therefore the document must be named, if this has not been done yet. If the document is already named, an automatic change is made to the "design new link dialog" in QueryPlus (see Section MS-Word Link or MS-Excel Link). There you can link saved SQL statements or saved queries with your document.
When adding links, captions for the particular position of the link data are added to your document. These captions are called SQLEntryBeginX or SQLEntryEndX, respectively, where X will be replaced by the number of the link for this document. The numbering starts with 0. In addition to these captions, brackets are inserted into your document. These brackets indicate that a link is available but has not yet been actualized.
If the captions are moved while you are editing your document, the link data at the moved positions is actualized as well. If captions for the data link are deleted, the links are preserved in spite of the deletion, because information for a link was stored in the database. If captions for a link are no longer available, the data is inserted at the insertion point after confirmation.
2. Actualizing Links
Actualizing links of a document initially serves to insert link data and then to actualize data existing in the document with data from ADABAS. If captions for a link are no longer available, the data is inserted at the insertion point after confirmation.
3. Modifying Links
You can modify links to change the data attached to a link or to release individual links from the document, or simply to show the links that are available to a particular document.
