Hi, If you have IBM File Manager (FM) you could use the Disk Browse or Edit functions available from option 5 on the main menu. For option 5.1 (Disk Browse) you provide the data set name. After you press enter the data at the start of the data set is displayed on a panel where you can change the location in the data set by entering a ccccchhh address value. See: https://www.ibm.com/support/knowledgecenter/en/SSXJAV_14.1.0/com.ibm.filemanager.doc_14.1/base/dbuse.html
For option 5.2 (Disk Track Edit) you supply the ccccchhh address value (or track number) along with the data set name on the entry panel. See: https://www.ibm.com/support/knowledgecenter/en/SSXJAV_14.1.0/com.ibm.filemanager.doc_14.1/base/dteuse.html Note these are IBM Data Interfile Transfer, Testing, and Operations Utility (DITTO) functions that have been included in FM. You can also do similar processing in a batch job using the FM DP (Disk Print) and DSR (Disk Record Scan) functions. See: https://www.ibm.com/support/knowledgecenter/en/SSXJAV_14.1.0/com.ibm.filemanager.doc_14.1/base/dpfun.html https://www.ibm.com/support/knowledgecenter/en/SSXJAV_14.1.0/com.ibm.filemanager.doc_14.1/base/drsfun.html Regards, Peter Van Dyke HCL Software On Thu, 18 Jul 2019 at 05:41, Binyamin Dissen <bdis...@dissensoftware.com> wrote: > On Wed, 17 Jul 2019 13:01:05 -0400 Billy Ashton <bill00ash...@gmail.com> > wrote: > > :>Hi everyone, I have an unusual problem.
