Editing a DELTA List
The DELTA List Edit panel is the main panel for a DELTA List edit session. From this panel, you can insert, delete, copy, and move elements and nested DELTA Lists within a DELTA List.
You can also mark elements for execution, add notes for the DELTA List, and view details about each element in the DELTA List.

Description
DELTA List
contains the DELTA PLUS PDS member name for the DELTA List
Title
An optional descriptive title of up to 30 characters can be entered in the Title field. The Title field enables you to provide a description for each DELTA List as an aid in DELTA List management.
With ISPF Version 2.3 or later, double-byte character set (DBCS) capable terminals (such as the IBM 5550) can edit the Title field in mixed DBCS/SBCS mode. DBCS-capable terminals can display titles that contain both IBM Kanji double-byte characters and standard characters.
Sorted by
indicates the order by which the elements in the DELTA List are sorted. The following sort orders are available:
- INSERT_ORDER - Elements are sorted by the order in which they were inserted in the DELTA List.
- MARK - Elements are sorted with unmarked elements occurring before the marked elements.
- ELEMENT_TYPE - Elements are sorted by element type.
- ELEMENT_NAME - Elements are sorted by element name.
- DELTA_ACTION - Elements are sorted by DELTA action.
- RENAME - Elements are sorted by the name in the Rename field.
- MODEL/MASK - Elements are sorted by the value in the Model/Mask field.
- LIMITING_IMSID - Elements are sorted by the value in the Limiting IMSID field.
- FND/CHG - Elements are sorted by the value in the Fnd/Chg field.
- DATA_CHECK - Elements are sorted first by INSERT_ORDER and then by the value in the Data Check field.
- NOTES - Elements are sorted first by whether or not notes exist for the element and then by INSERT_ORDER.
You can change the sort order by moving the cursor to the Sort menu on the action bar and pressing Enter, or by typing the SORT command on the Command line. Select the appropriate sort option.
The sort order determines which action codes are available. The INSERT_ORDER sort order must be used for the I(Insert), C(Copy), M(Move), A(After), B(Before), and O(Overlay) action codes to be available.
Excluded
indicates the number of elements excluded from view
Marked
indicates the number of elements marked for execution. Elements not marked for execution can be bypassed at execution time by using the option Execute Marked elements only on the DELTA List Execution panel.
DELTA List is dependent
A mark in this field designates the DELTA List and the changes contained in it as dependent. This designation ensures that all the changes must complete successfully for all the elements in the DELTA List on the target IMS system or none of the changes are applied.
Variable Definition Set
Specify the name of the member (the Variable Definition Set) in the Variable Definition Library that contains the variable definitions for this DELTA List. The Variable Definition Sets are members that contain the definitions for the symbolic variables used by DELTA PLUS in DELTA List processing.
To specify a default Variable Definition Set that will automatically be inserted into this field each time you edit a new DELTA List, enter the PREF command.
Note: This value can be overridden at DELTA List execution time.
Actn
Type one of the following action codes in this field next to one or more of the elements listed on the panel:
- A - After (only available when the INSERT_ORDER sort order is used)
- B - Before (only available when the INSERT_ORDER sort order is used)
- C - Copy (only available when the INSERT_ORDER sort order is used)
- D - Delete
- E - Edit the DELTA List
- I - Insert (only available when the INSERT_ORDER sort order is used)
- K - Mark
- M - Move (only available when the INSERT_ORDER sort order is used)
- O - Overlay (only available when the INSERT_ORDER sort order is used)
- R - Repeat
- S - Detail
- U - Unmark
- X - Exclude
These actions are performed for the element in relation to the DELTA List. See Step 7 for more instructions on using this field.
Mk
A / in this field indicates that the element is marked for execution. You can also select this option while editing an individual element.
An asterisk in this field indicates that the element is a comment element. The remaining fields in the row contain the comment text.
Element Type
identifies the type of the IMS system resource element in the DELTA List. Possible values are
- APPLCTN - application programs that run under the control of the IMS DB/DC environment
- TRANSACT - IMS exclusive, IMS Fast Path potential, or IMS Fast Path exclusive transactions
- DATABASE - a physical database that IMS manages
- RTCODE - route codes
- TERMINAL - IMSGEN-defined terminals
- LTERM - IMSGEN-defined LTERMs
- SUBPOOL - IMSGEN-defined subpools
- COMMAND - selected IMS operator commands
- DELTALST - a DELTA List nested, or embedded, in the parent DELTA List
- COMMENT - user comments
Element Name
identifies the name of the IMS system resource element in the DELTA List
DELTA Action
identifies the DELTA Action that should be taken against the associated IMS system resource element. Possible values are
- ADD
- ADD/REVISE
- REVISE
- DELETE
- RELOAD
Rename
identifies the new name to which the specified element should be renamed in IMS
Model/Mask
identifies the name of the existing element on which you want to base, or model, the selected element
Limiting IMSID
specifies an IMSID that is used to restrict the target IMSID for a DELTA List Check or Execute. When specified, a DELTA List Check or Execute will only be allowed for IMSIDs that match this mask.
Fnd/Chg
indicates whether the element was found with the FIND command or was changed with the CHANGE command.
Data Check
indicates if the element contains data errors. An element with errors cannot be executed.
Decide which edit action you want to perform. Perform the appropriate action.
Activity
Action
Copy an element within the DELTA List
Type the C action code in the Actn field next to the element that you want to copy.
Use the A(after) and B(before) action codes to indicate where in the DELTA List you want the selected element to be copied.
Type the A(after) or B(before) action code in the Actn field next to the element where you want the selected element to be copied before or after in the DELTA List.
Press Enter.
The C, A, and B action codes are only available when the INSERT_ORDER sort order is used.
Delete an element from the DELTA List
Type the D action code in the Actn field next to the element and press Enter.
DELTA PLUS delete element requests can be included in a DELTA List for databases, applications, transactions, and route codes only. When DELTA PLUS is used to delete one of these IMS elements, it does not physically remove the control block from IMS storage; instead, it sets a delete bit on in the control block, thereby making it unavailable for use. The element cannot be displayed or used with IMS; however, it remains in virtual storage. Subsequent attempts to delete these already deleted elements are ignored, no error message is generated, and delete processing continues.
Edit a DELTA List nested within the DELTA List
Type the E action code in the Actn field next to the DELTA List and press Enter.
Insert an element in the DELTA List
Type the I action code in the Actn field next to the element and press Enter.
See Inserting-a-DELTA-List-element for more instructions.
The I action code is only available when the INSERT_ORDER sort order is used.
Mark an element for execution
Type the K action code in the Actn field next to the element and press Enter.
Move an element within the DELTA List
Type the M action code in the Actn field next to the element that you want to move.
Use the A(after) and B(before) action codes to indicate where in the DELTA List you want the selected element to be moved.
Type the A(after) or B(before) action code in the Actn field next to the element where you want the selected element to be moved before or after in the DELTA List.
Press Enter.
The M, A, and B action codes are only available when the INSERT_ORDER sort order is used.
Overlay another element in the DELTA List
Type the O action code in the Actn field next to the element that you want replaced. Type the C action code in the Actn field next to the element that you want to replace the other element.
Press Enter.
The O and C action codes are only available when the INSERT_ORDER sort order is used.
