For a list structure allocated to use keyed entries, the IXLLSTE service can be used to assign a new entry key to a moved list entry. Use the MOVETOKEY keyword to:

• Keep the current entry key of the list entry (MOVETOKEY=UNCHANGED).
• Assign a new key to the list entry if it is moved (MOVETOKEY=TARGETKEY). The assigned entry key is used in conjunction with MOVETOLIST and MOVETODIRECTION to designate the target keyed position of the list entry.
• Assign the current list key value of the target list to the moved list entry (MOVETOKEY=LISTKEY). Note that if you chose to increment the list key value after assigning it to the entry key and the resultant value is greater than the maximum list key value, the IXLLSTE request will be terminated.
