[basex-talk] SET command?

Having a weird behavior with the SET command as I can'r seem to change any option. Just launching from the shell using the "basex" script, I can GET but not SET. I must be doing something obviously wrong.... This is with 7.6 on MacOSX.

BaseX 7.6 [Standalone] Try help to get more information.

GET DBPATH

DBPATH: /Applications/basex/data

SET DBPATH /Users/Pascal/BaseXData

Unknown option 'DBPATH'.

GET LANG

LANG: English

SET LANG French

Unknown option 'LANG'.

Also tried: basex -c "SET DBPATH /Users/Pascal/BaseXData" but same results.
