Macro for 'Worksession Open'

Hello! Simple question:
I’d like to directly open a .rws file via a macro. Yet

_Worksession -Open

… still brings up the worksession dialog window. How to suppress it?
Thanks!
Best regards
Eugen

Try
-_Worksession O

Move the dash to the front of the macro.
The dash is the trigger to run the Command line version of the tool.

That did the trick, thank you John!
Using
-_Worksession O B
to get a file browser directly.
