If a user program in CICS passes control to another program with LINK command and if the linked program issues a EXEC CICS ABEND command will that cause a storage violation in CICS region?
No. There is no reason an EXEC CICS ABEND will cause a storage violation unless the transaction, or some other application, has already corrupted storage in such a way as to create a second storage violation as a by-product. If you are not already doing so you should investigate using storage protection and transaction isolation to help track down the problem and avoid such problems in the future. For an overview of storage protection and transaction isolation see the CICS Application Programming Guide SC33-1688 for CICS TS V1.3, SC34-5993 for CICS TS V2.2).
