DD-VSE DLBL/TLBL definitions

Edit online
There are three DD-VSE DLBL/TLBL Definitions process statements:
NEWDD
Name applies to the new (or search) file
OLDDD
Name applies to the old file
UPDDD
Name applies to the update file
For z/VSE® sequential files, these process statements allow you to specify:
  • Alternative names for the new and old input files, and for the output update file. (The default names are NEWDD, OLDDD, and UPDDD.)
  • The file attributes for the new and old input files. (The default attributes are: non-VSAM, fixed, unblocked, record size 80).
For z/VSE Librarian members, these process statements allow you to select members from the new and old sublibraries.
Notes:
  1. NEWDD, OLDDD, and UPDDD process statements as discussed in this section apply to z/VSE only. See also DD-MVS alternate DD names.
  2. When NEWDD is used in the SuperC Search, references to the new file in the following pages indicate the search file.
  3. For more information about the Job Control Language (JCL) required for the new (or search), old, and update files, see Invoking the comparison on z/VSE and Invoking the search on z/VSE.
