Rational Developer for System z, Version 7.6

Level, address and length

The Level, address and length tab gives you information on the elements called in the Segment, such as their COBOL descriptions. You also find statistics on the current Segment.

The Level, Address and length tab is the equivalent of -LAL and -STA in Pacbase Transactional programs. It consists of two tables whose data items are tightly linked to the information you enter in the -CE lines tab of the Segment's editor.

Statistics

The fields of the statistics section are automatically completed. If you add or remove an element in the -CE lines tab, statistics are updated simultaneously.

If you add a Data element call to the Segment, or remove one of them, you can see the Number of Data Elements field being updated ; it is the same for a Segment, the Number of Segment calls field is updated ; and for a Filler, group, Elementary Data Elements call added, this is the Number of Elementary fields field that is modified. You can cancel this action via the popup menu, choice Undo. As a result, the fields in the Statistics section are reset to their initial values and the line call is removed from or re-inserted in the -CE lines of the Segment. A Redo action is still possible.

If you have done a series of updates in the -CE lines of the Segment, and you have not saved yet these changes, you can still revert to the last saved updates. Do do so, choose Revert in the statistics' popup menu.

Segment
Name and label of the Segment.
Number of Data Elements
Number of Data Elements called in the Segment, in the -CE lines tab.
Number of Elementary fields
total number of elementary Data Elements and fillers called in the Segment, in the -CE lines tab.
Input length
the total of the elementary fields' input lengths calculated with the input format indicated in the Data Elements editor, in the Definition tab.
Internal length
the total of the elementary fields' internal lengths calculated with the internal format indicated in the Data Elements editor, in the Definition tab.
Output length
the total of the elementary fields' output lengths calculated with the output format indicated in the Data Elements editor, in the Definition tab.

Level, Address and Length

Next to the Statistics section, you find in the Level, Address and Length tab, a table including information indicated in the Definition of Data Elements such as the Usage, the Internal format, the output format with the length and address of the Data Element called. If a Data Element is redefined, the length of the redefined Data Element is taken into account. If the element called is not a Data Element, the numbers displayed in the Internal format and Input format columns are always identical. The Occurs values are those entered on the definition of the element called in the Segment's -CE Lines tab.

Possible actions in this table via the following choices in the popup menu:
  • Undo: you can cancel the last update you made in the -CE lines tab. As a result, the line corresponding to the element called in the Segment is updated in the 'LAL' table.
  • Redo: you cancel the last undo action.
  • Revert: You cancel all the last unsaved updates you made in the -CE lines tab. As a result, the lines corresponding to the elements called in the Segment are updated in the 'LAL' table and you revert to the last saved changes.
