Data Item (m604804+dataitem.htm)
Like the dictionary items described in this section, user data in a data section is arranged in items. An example format of a data item is given below.
| Attribute | Description |
|---|---|
| Item-id | 309 |
| 001 | 8232 |
| 002 | Mendell |
| 003 | Robert S. |
| 004 | 545 Parker Ave |
| 005 | New York |
| 006 | NY |
| 007 | 10022 |
| 008 | USA |
| 009 | AMEX |
| 010 | 2]2]2]15 |
| 011 | 8247 |
| 012 | 78.00]34.00]78.00]5.87 |
The example above is taken from the data section GUESTS in the English-TUTORIAL account which is a system account provided on a newly created database.
Data is provided in attributes 1 to 12 as shown. The attribute line number corresponds to the attribute mark count in attribute 2 of the data definition items in the file dictionary, in this case, DICT GUESTS. Hence, the data definition item with AMC equal to 1 (item-id is ARRIVAL-DATE) describes the English format and processing of data in attribute 1 (8232).
In this example, the date is stored in internal format (8232) and the data definition item ARRIVAL-DATE contains the conversion code in attribute 7 to convert the date to external format. Other definition data in the ARRIVAL-DATE item formats the Arrival-Date column in an English report.
Similarly the Name and Address data in attributes 2 to 8 is formatted in an English report by data definition items with AMCs 2 to 8 and so on.
See the topic Data Definition Item and the English Reference for more details.
