From Windows command line

SWI-Prolog is started from the Windows taskbar by clicking an icon (shortcut - *.lnk) , the shortcut uses this command line
“C:\Program Files\swipl\bin\swipl-win.exe” --win_app
The Windows install wizard noted the Python interface
The file janus.pl line 93 shows
:- use_foreign_library(foreign(janus), [visibility(global)]).
At this point not sure if the DLL was created automatically or I need to create it but will run that down; just wanted to give you some rapid feedback.
