Radoslaw, I suggest you change the region to 0M. We document that under Joinkeys application notes. Since a JOINKEYS application uses three tasks, it can require more storage than a regular DFSORT application. You may need to use REGION=0M for some JOINKEYS applications. https://www.ibm.com/docs/en/zos/2.4.0?topic=files-joinkeys-application-notes > Now it's time for learning - while I can use some statements I do not > necessarily know what can I put together in single SYSIN command set. > Sometimes I meet the goal within few steps instead one. :-) Joinkeys is a two file match technique and the examples in the application programming guide and smart tricks should give you a good idea about Joinkeys. Check out these sample topics to showcase the power of joinkeys. https://www.mvsforums.com/helpboards/viewtopic.php?t=12781&highlight=joinkeys https://www.mvsforums.com/helpboards/viewtopic.php?t=12780&highlight=joinkeys As always you can always post your requirement here or send an offline mail and I will try to help out Thanks, Kolusu DFSORT Development IBM Corporation ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
