This version of
Data File Tools (Technology Preview) has the following restrictions:

if your effective working mode (cobmode) is 64-bit (UNIX).
- The only supported UNIX platforms are SUSE and Red Hat.
- There is no support for Unicode files.
- There is no file conversion functionality; use the DFCONV command line utility if you require this functionality.
- There is no support for old structure (.str) files and profile files (.pro files), produced in Classic Data File Tools. This version uses a
.dfs structure file to contain the information previously held in the other two file formats.
- All files are opened in
Data File Tools (Technology Preview) using a lock mode of EXCLUSIVE.
