Reassigning ISN

Hello Everybody,

My question is : When a record is deleted from Data Storage, can the ISN be reassigned to another record. If no why?


This depends on the setting of the ISNREUSE parameter to ADALOD, the default is NO

From Natural’s point of view you would use a STORE with NUMBER-option. Of course you can use this option only if ISNREUSE is ON…


Actually, I believe if you are assigning the ISN, you can reuse ISNs, regardless of the ISNREUSE setting - ISNREUSE is only for Adabas-assigned ISNs.

You’re right. I tried it out today. USING NUMBER also works, if IRSNREUSE is OFF.

… Sorry :oops:
