I agree with Howard, unless you're ready to use a Database solution and write directly to the database then I would log the data as @WKSTA+'.TXT'

Then use another process either KiX or batch and copy all the log files into a single file?

Depends on how you want to process and report on this data.

The datase solution is not without potential errors either. There are many, many things that can cause a write or connection failure. Detecting and dealing with that within KiXtart is not a trivial task for a new user.

Aside from that EVERY solution aside from a database that writes to the same file can potentially have locking issues except the method described by Howard.
