DFSORT latest version??

[rinki]

I was trying DFSORT with JOINKEYS in the sort control cards and got the error as below(RC=16).
It seems the current version (V1R5) of DFSORT does not support JOINKEYS.
Is it possible to upgrade the current version by installing the latest PTFs available?
Sorry for the inconvenience if any.

The PTFs UK51706 and UK51707 needs to be installed for joinkeys to work.
Also the PTFs UK90025 and UK90026 will bring it to the current level.

It's highly unlikely that DFSORT (or any other software) will be upgraded. Use what's available, and find a workaround.
