Thanks for all your responses. To get the JNI routine to work I made the assembler routine re-entrant and linked the JNI routine RENT; the JNI routine now resides in key=0 storage.

Was there any benefit in doing so? Is Content Supervision guaranteed to continue to respect independence of those attributes? ________________________________________ From: Paul Gilmartin <0000042bfe9c879d-dmarc-requ...@listserv.ua.edu> Sent: Wednesday, February 15, 2023 6:59 PM > ... >Reentrant: You can invoke the module concurrently from multiple tasks and >get correct results.

Formerly, a module might have been marked refreshable because it was read-only code, but not reentrant because it relied merely on that property to serialize its access to an external resource. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN -- This e-mail message has been scanned and cleared by Google Message Security and the UNICOM Global security systems.
