You can resolve the problem via JCL and leave the program alone. Have the output be three or more separate temporary data sets. Tnen follow that step with steps to copy the temporary data sets one by one into the original target PDS. Use DISP=OLD to ensure no other job/user is writing to the same PDS. If you can be certain no one else will be updating it, then DISP=SHR will suffice. This would be typical, for instance, if the output PDS was allocated to a long-running task or to multiple tasks, such as a JCL library owned by the scheduler using it as read only, or ISPF panel/message/skeleton libraries allocated to many TSO users for input. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
