Thank You!
I've managed in other way. I found 'workbench/startup' module with wbstartup object defined.
In short:
Code:
...
MODULE 'workbench/startup'
...
DEF startup:PTR TO wbstartup, args:PTR TO wbarg
...
startup := wbmessage
args := startup.arglist
WriteF('\s\n', args[].name)
...
Done in hurry, without any error handling.

But it works.
