Primary commands of segment/layout XREF screens

The following primary commands are available in the Segment/Layout XREF screens.

CANCEL

Terminates the XREF edit session without performing a save operation. All changes made since the last save are not reflected in the XREF. The Segment/Layout XREF - Dataset Specification screen is displayed.

DELETE

Deletes an entire DBD from the segment/layout XREF. Deleting a DBD from the XREF has no affect on your corresponding DBD load module member.

END

Terminates editing of the current XREF and displays the Segment/Layout XREF - Dataset Specification screen. If any changes were been made to the XREF member since the last save, a save operation is performed.

INSERT

Adds DBDs to a segment/layout XREF. During insert processing all segments defined in the DBD are added to the XREF. The newly inserted DBD is added in alphabetical order by DBD name and the XREF Segment List screen is automatically scrolled to the inserted DBD. The segment names defined in the DBD are prefilled in the Segment field of the screen. Because concatenated and logical child segments are automatically identified during insert processing, *CONCAT* or *LCHILD* is displayed in the Member field for those segments. Otherwise, the segment names defined in the DBD are prefilled in the Member field. How to specify segment layout information for concatenated and logical child segments and segments with multiple formats is described later in this section.

You must define only one DBD member per XREF member that matches the XREF member name with the DBD member name.

RETURN

Returns to the Primary Option Menu or to the specified option, if any. As with the END command, changes made to the XREF since the last save are written to the XREF dataset.

SAVE

Writes the segment/layout XREF information back to the same data set from which it was read. The library statistics for the member are updated. The save operation checks that segment layout information was specified for all logical child and concatenated segments and for segments with multiple formats. Unspecified segment layout information for these types of segments does not result in an error condition until you attempt to save the XREF with an END, RETURN, or SAVE command.
