Activities

To reach the relevant display, proceed as follows:

  1. Branch to the attribute display by choosing the function Start of the navigation path GoTo Next navigation step Display Data Object Next navigation step { Single Field | Structured Field | String | Internal Table | Object } End of the navigation path.

  2. Enter the name of the data object and choose ENTER, or double-click the data object in the source code.

  3. The following information is then displayed depending on the data object you selected:

Single fields

Name, field contents, type, length, output length, decimal places

Struc. Fields

Name, length, number, component name, type, length, contents

Strings

Name, type, current length, content

Internal Tables

Name, type, format, line number, line contents

Objects

Name, class/interface, number, attributes/interfaces, type, length, contents

If you want to display more information in the attribute overview on particular fields of a structure, table or class, open the detail display by double-clicking the appropriate field. Choose Back to return to the overview.

If you enter the name of a single field in the attribute display for a structured field, the system switches automatically to the single field display. Likewise, if you enter the name of a structured field in the attribute display for a single field, the system will switch to the structured field display.

Displaying Data References

If you double-click a data reference dref in the Field Names column, information on the technical attributes of this are displayed. If you double-click the Field contents column, the contents of the data reference are displayed. The referenced object is displayed when you double-click the data reference dref->* in the Field Names column.

Displaying the Unicode Fragment View

When selecting the menu Start of the navigation path GoTo Next navigation step Display Data Object Next navigation step System Information End of the navigation path the Unicode fragment view is displayed. In this view, structures, internal tables, strings, data references, and objects are split into alignment gaps, byte and character-type areas, and all other types such as P, I, F, strings, references and internal tables.

Adjacent character-type components of a structure (with the exception of strings) are combined internally to form exactly one group if there are no alignment gaps between these components. All possible alignment requirements for characters are taken into account here. Adjacent byte-type components are also combined in the same way.

Additional Functions

  • The Single field display mode, like the Fields mode, can be used to change the contents of a field or display them in hexadecimal format.

  • In the Structured field display mode, you can show and hide substructures.
