Changing default insertion of EOF track during COPY with ALLDATA specified (OW15003)

When multivolume sequential data sets are copied to a single-volume like device and ALLDATA is specified, the default action inserts an explicit EOF track in the target data set, when required. A patch is provided that allows an installation to change this default. If the patch byte at offset X'1D' of module ADRPATCH is set to X'FF', no explicit EOF track is added to the target data set.

To set the flag to on dynamically, use the SET PATCH command. To set the flag to on permanently, modify the sample JCL (see Sample JCL) as follows:

//SYSIN DD *
   NAME ADRDSSU ADRPATCH
   VER   1D        00
   REP   1D        FF
